I was trying to start a 1.16.5 modded server and it worked fine during startup, but as soon as it started the console filled up with errors and it crashed after a little while. I'm using the latest version of MCMT on forge 35.1.37
heres the logs: latest.log

Hello I am modpack maker and for me only thing that matters is performance and stability. 1.15.2 fps are much worse than 1.12.2 btw. I am just wanna know is there will be 100% 1.12.2 port or is this questionable.
I am know this was asked before.

Players are randomly kicked out of the server after a period of time. Once kicked out, they cannot connect until the server is restarted.
Other players can play the game normally (until they also encounter or quit the game), the server will not crash and there is no failure log, and the server cannot accept new player logins.
The server will receive the message that the player joins and the player exits, and the client displays the connection timeout after joining the world.
This may be due to an unpredictable conflict with the module or a thread listening for some reason throws an exception to stop the player from entering the game.

Hey this is more or less a question of mine. So as we all know Gpus have a lot of power and minecraft dont touch that power at all. I searched a bit for what effect it could have if we run the minecraft worldgen on an Gpu and in theory this is a big deal. So my question is can add a worldgen or other features like this too this mod to harness that power?
I basicly allready know the answer. Its way to complicated to make this happen. I think I just want to inspire people that are way better at programming then me or you so at one day we could have it.
maybe...

This error showed up in my game console with the Rats mod. Nothing really noticable happened, just thought I should report it to you.

not quite sure about what is happening here fire starts spreading randomly around the world w/o reason and afther a short time the world crashes.

The server starts fine but doesnt respond to commands and on trying to log in players time out. Runs fine on my local server except this remote server. Also the only way to stop the server is to kill the process since it doesnt respond to commands.

Hey again, I'm running a 1.15.2-forge-31.2.45 server with MCMT 0.18.60, and I've encountered a few problems regarding the chunk provider and tile entity multithreading.

First off, glass item frames from the Quark mod (although it may occur with any item frame), generally those close to chunk borders, are broken randomly with both the frame and the item it contained falling to the ground whenever the chunks with those frames are unloaded and reloaded (either by restarting, leaving and joining the server, or by going into other chunks and returning). The item frames are unable to be placed back unless the chunks are unloaded and reloaded again, although /reload does not work. No message in console is displayed when this occurs (see image attached).

Next, iron doors or any other type of door placed next to a chunk border cannot be opened by pressure plate, button, or any other method when chunks are unloaded and reloaded. However, the items used to open these doors work on other items placed next to them that are not near the chunk border, and the doors themselves work when moved away from the border. The doors also seem to snap back to the border when placed on a block running alongside the border, until they are interacted with via fist, in which case they glitch. However, this issue stops whenever ChunkProvider is toggled off, and the doors work temporarily again even once it's reenabled. However, ChunkProvider being toggled results in heavy console spamming, usually about invalid tile entities and such (this doesn't occur when the command toggling off everything is run, though). This eventually results in the entire server crashing due to ticking world, and items in chests or tile entities vanish.

Finally, when loaded into a chunk with a lot of hoppers and other tile entities, console is spammed considerably, and TPS dips as well. This stops when TE multithreading is toggled off, though.

This is just a question: is the syncfu.jar available for the 1.16.3 version? If so where would the download happen to be? Would defiantly like to give this mod a try, but would prefer to have both if it helps with stability.

LevelBasedGraph is used a lot (Esp. in world level stuff) and appers to have edgecases where it breaks

However those edge cases mostly seem to be related to vilage code so it may be that that need poking instead and the general case can be parallelised (which would be good)

Notes:

• Currently processUpdates and scheduleUpdate are synchronised to fix the issue
• The synchronisation region could be reduced to just cover a small section of the executed code, potentially allowing multiple things to loop just not fetch at once

i thought i would give this mod a shot if used tick threading before im used to crashes and unstable with this type of work thus i will post the logs in the hope of a fix.

Effects randomly stay on players (0:00) on 1.16.3-forge-1.34.1 server with only MCMT installed, also tried to disable Entity Parallelization but didn't help.

Noticed with beacons and tested with beacons for fast effects iteration, after removing MCMT, the issue is gone.

Occasionally the world updating breaks in a way that animals no longer breed and blocks can no longer be broken. Seems a lot like being ticks behind and getting block lag, but it does not report so in the log. instead the log gets spammed with

This mod list has been stable for a few weeks, but struggled due to being bound by single core performance. With your mod installed it runs very well and never falls behind, aside from this hangup. I can provide more detailed logs as needed. If you have any insight it would be fantastic.

On a side note there may be a conflict with horse_colors-1.15.2-1.4.0.jar that results in horses always having twins? have not fully diagnosed yet.

Hi, i love this mod! Do you plan to add support for 1.12.2?
After all, most of the mod servers run on this version, and it, in turn, is a successor to the old 1.7.10.
This would solve a lot of performance issues!

Make a 1.8 version of this mod, it will be usefull among PVPers.

I tried using only MCMT and Serene Seasons alongside eachother, downloaded the most recent versions of both mods. It is not a serene season issue like I had originally thought, after uninstalling MCMT it gets fixed and works with 100+ mods.

Issue: Server Log is filled with spamming of "season time skipped in (enter dimension here) every second, includes every single dimension except the one whitelisted in the serene season config. meaning only the overworld isn't involved with the spam, but this makes the server log clutter so unbelievably fast, I had shown this log to a couple other discords and I guess it has something to do with MCMT because once I remove it, it's entirely fixed.

Here is a couple logs to go with it, I wouldn't say its a "incompatibility" issue, I'm just looking for a way to filter out that spam in the log, and from what I've researched over the past month nothing for forge 1.16.5 can take a user input into a config file and filter out whatever it outputs

On version 1.16.4, mostly found when loading new chunks, but several crashes were also in general gameplay. I removed performant and yet the crashing continued. Another issue, the server tickrate with performant installed dropped significantly with the world option of mcmt toggled on, after removing performant or disabling world, worked fine until crashes. Attached are several crash reports.

https://pastebin.com/zN4tAd2L

This first one crashed while loading new chunks, and have had several crash reports not unlike this one, looking into them I saw the chunkprovider was mentioned a lot, tried turning that off with MCMT, the crashes persisted.

https://pastebin.com/WM376n44

This one is quite similar to the first, and seems as if they are the same cause here.

https://pastebin.com/fGHC2yd9

There is a third, I hope these are helpful

I've tried updating the pack to 3.1.3, and the problem persisted, thank you for all that you do in making this mod, it truly is amazing.

Here's the logs, https://paste.ee/p/5EAnq

Good luck with this project!

attached are debug logs from java 8 and java 14 + the ZGC garbage collector. Java 8 appears to work fine, while 14 causes ticks to completely stop shortly after loading a world. once this happens, closing the world gets stuck on "saving world" and needs to be ended with task manager even though it's still responding. Possibly happens when generating fresh chunks, not sure.

Well this is not at all an Issue. I'm just trying to help out the developer by testing the mods for different versions with MCMT. You can help too and write your experience with the mods in the Card comments. To test the mods I'm using the last version of the mod and the last version of forge. Core mods are not listed because you can't test them. I always get my mods from curseforge or the official website from the mod, because this is the most likely place to look after mods someone who does not have that much experience with them. If you have any questions to my test result or want to be a member for helping test mods just ask me.

Hello Ur mod is great but i found some bug in it all threads are stuck on 20% of utilization and cannot go further but tps is going lower lower and lower because of this lock.

Hi, I'm running a 1.15.2-forge-31.2.45 server with MCMT 0.18.60. Whenever the server starts and I attempts to join, console is spammed heavily before the entire server freezes. Then, the server crashes due to a single tick surpassing 90 seconds. The server appears to start fine, though. It also runs for a few seconds before the freeze, and I am capable of loading in. I've added the syncfu file as well, as without it I was unable to load in at all. I also tested with version 0.17.54, and the same thing happened.

I tested MCMT in the newest version of forge 1.16.4 and run into some problems. During World gen it puts out error about it could not save the chnk it generated but the server and the world seemed to be fine. At some point the server just crashed without me doing anything. I didnt had any other mods installed.
Here are the errors:
Chunk Error 1.16.4.txt

The server Ram has also some Spikes? while world gen.. It gets around 4Gb but then resets to about 500Mb.

Pistons are the only vanilla thing that doesn't multithread and that is bad

It should be made unbad

By fixing it

Notes:

• This is technically due to a two pronged issue, as piston moves are handles in part by BlockPiston, and in part by TileEntityPiston so breakage can occur. IDK how, but apparently it can
• TODO: more info

Hey, when we used this mod on our ATM 6 - 1.16.5 Server, on every Player there spawned about 200 Fish or other mobs and that is not funny :(

I run about 175 mods in 1.16.4. After quite a bit of testing I actually noticed slowdowns, specifically with rendering. I know that the mod was intended to be used server side. However I am trying to test exactly how many mods I can use so that I know what type of server I will need. As you said on curse, an option to limit the number of cpu cores or threads would be amazing to use.
Contained below is the logs that repeated for as long as I remained loaded into a world. I tested by loading into multiple works and noticed the same issue. I am sorry I could not post more specifics, however I need to head to sleep for work, so if you need more specifics I can drop them for you. Still, amazing TPS impact, I look forward to seeing more use of this mod in the future!

Hi.

At the moment, the mod does not support Minecraft 1.16.3. Please could you add support for this?

Thanks!

Version: 1.16.3
Forge Version: 34.1.7, tested 34.1.0 and 34.1.1
Mods Installed:

• Inventory Tweaks 1.16.2-1.0.0
• JEI 1.16.3-7.3.2.36
• JMT-MCMT 0.17.54-1.16.3
• OptiFine 1.16.3 HD U G3

Problem: Generating/loading worlds will stop at 100% permanently if OptiFine is installed. Game needs killed.

Logs:
2020-10-05-4.log.gz

Notes:

• I've noticed that in the logs, it says "Preparing spawn area: 0%" but the screenshot shows 100%.
• The mod works fine without OptiFine installed.

This is the big one; it is what makes redstone go and fluidst flow (I think they are both similar systems)

Parallelising this will be !!FUN!!

As in, expect everything to break

Notes:

• Am tired so notes are hard to write
• I beliefve these are handled by ServerTickList's, but I may be confusing the subsystems (again tired sorry)

When this mod will be on 1.12.2. Does it will work with Cubic Chunks????
If no can U please do all the things that U can to make it work.
I really need cubic chunks for my modpack.
Making video about Ur mod is deleyed a bit cuz I am ill.
Best Regrads!!!

When doing a stress test to see how the mod would behave when the maximum amount of threads are being used, I noticed an issue with framerate. I believe this is due to too many threads being spawned, causing the render thread to have trouble running often enough and therefore tanking framerates.

A possible solution could be to set the max amount of threads to be something like this (psuedocode):

if (integratedServer) {
    Math.max(availableThreads - 2, 2);
    // use a minimum of 2 threads but a maximum of (CPU threads - 2) so that the
    // render thread, OS, JVM's JIT and GC have room to breathe.
} else {
    Math.max(availableThreads - 1, 2);
    // servers don't have a render thread and not many cores, they also usually have
    // a headless OS, so only deduct 1 from the available CPU threads to make better
    // use of the HW while still giving GC, OS, JIT and plugins room to breathe.
}

By the way, thank you for your efforts on this mod - it's impressive how this mod manages to achieve so much more server-side performance compared to Vanilla with a decent amount of cores!

Hey,
I tested this mod for an while now on my server(all the data down below) and I notice that while generating new chunks all threads are being used, but only running between 10% - 15% load.
This is not the case for other loads. For example when I spawn a few thousend mobs the load an the cpu cores is scaling properly.
I hope this can be fixed it whould give me the last push to switch from 1.12.2 to 1.15.2.
I also hope you will continue working on this mod because its so powerfull and can bring some new life in servers.
