Sometimes the client-warp works fine. But after the connection finished, the server-warp will print logs like this:

Should I just ignore the memory leaks?
Thanks,

Sometimes the server-warp would encounter the same errors as the client-warp. And when it happens, the dmesg reports logs like this:
[88830.767128] ixgbe 0000:89:00.0 ens4f0: NIC Link is Down
[88832.057506] ixgbe 0000:89:00.0 ens4f0: NIC Link is Up 10 Gbps, Flow Control: TX

[88834.921311] ixgbe 0000:89:00.0 ens4f0: NIC Link is Up 10 Gbps, Flow Control: TX
Shoud it be something to do with netmap?

The leaks are something I need to fix. As I said, I haven't used quant with netmap in a while, and quant has changed a lot.
As for the abort, are you on the latest versions of quant and warpcore? I thought I had fixed that yesterday.

commented on August 25, 2024
Yeah.. I'm on the updated version but unfortunately, still encounter this issue. This happens randomly on client-warp and server-warp side. I repeated it several times and sometimes it did succeed, but only in the Debug version. In Release version, it always encountered the abort issue (on my machine).
Not sure if this is because there is something wrong during my build process. So I think it might be better to have a look at it here if you have any time :)

Build looks fine.
The abort is likely due to some recent changes in my socket hash code. Basically, it tries to remove a bound socket from the hash to reinsert it as connected, but fails to remove it. If you instrument ins_sock and rem_sock and the related hash and comparison functions, you might be able to track it down. Otherwise I will look into it when I am back at work Jan 7.

I can't reproduce this on the current version.

commented on August 25, 2024
Sorry for the delayed reply, I was involved in something else.
Just tried again (with the newest code) and it can still be repeated. I'll try to track it and will update it here.
One more thing, I noticed that every time after I ran client-warp or server-warp, the ip_address on that NIC would lose. Not sure what caused this and if this is something that can be fixed?

Are you running IPv4 or IPv6?

It works fine on IPv6, but encountered problems on IPv4.

Weird. Can you do git rev-parse HEAD in the main directory and in lig/deps/warpcore and post the hashes? I want to make sure that you are really on the current versions; I can't explain why you see issues.

You are several version behind on both of these (mid-December).

Well.. every time I ran the experiments, I would use git pull first.
I checked on the master branch and the hash matches with the version of yesterday, as posted here:

Should I switch to another branch to get the latest updates?

larseggert
commented on August 25, 2024
Well, as you can see at https://github.com/NTAP/quant/commits/master there are newer versions (same for warpcore.)
What does git pull show? Do you have local modifications that would prevent it from updating?
from quant.

commented on August 25, 2024
Thanks for the detailed help. Finally made it work.
The stupid reason being that I forgot to use git submodule --init --recursive to update warpcore, after updating warpcore that, the hash values becomes :
9987c8a3f98588a5cb6f602d28994b4faf8b1650 for quant
4c715160a5a138cd4624265b92f9b9cb8f4aa57f for warpcore
Which indicates I should be on the latest version for both. And it works just fine on both IPv4 and IPv6.
Thanks again!
