I see similar failures occasionally locally, but rarely enough that it's been hard to debug. I just hit it twice in a row in full test suite runs while working on something else, but when I tried running just an affected subset of tests 100 times in a row I only saw a single failure. Most of the failures amount to a failure to receive a channels message after a 0.1-second timeout, so I'd suspect that bumping the timeout might help, except that there are also occasional failures about receiving a message after a 0.1-second timeout when we didn't expect to (as seen in https://ci.debian.net/packages/d/debusine/testing/s390x/56196441/#L8797). So it feels as though something a bit deeper is wrong here. It's possible this is https://github.com/django/channels/issues/2025, which might suggest some possible workarounds. -- Colin Watson (he/him) [cjwat...@debian.org]
