Dramatiq workers hangs very often, no logs were seen in logs even if it is verbose mode. about dramatiq

We got something similiar with --process 1 --threads 2. When Worker consume one queue and produce messages to another.
We reproduce it yesterday and will investigate what happend actually

Quick fix was --process 1 --threads 1
UPD: we produce messages to another queue trough kombu and kombu.Connection not thread-safe. In that case you got infinity wait on _read, cause bot threads call _read and read different parts of incoming data and both can't construct frame and infinity wait for next data.

I am seeing this as well running with --processes 4 --threads 1 running through django_dramatiq
I'll try updating to 1 process and see how that goes. Also using dramatiq 1.5 (python 3.10)

I've observed similar behavior when the CPU reaches 100%.

I have the same issue with 1.15 (python 3.11) using the AsyncIO middleware.
using --process 1 --threads 1 works
