I have seen this log which  indeed requires further investigation.

Is the latter causing test failure? python has GC (garbage collector) and I believe this is coming from the latter, so not really sure how to tackle this.

Checking more in depth the logs of the release 2.3.2, there in common three warnings that were not appearing before, are present in fedora24, fedora 25, ubuntu1604 an centos7a, the tests of oe-selftest happen.

Is this bug about the warning or the hang?

We see the warnings in builds which don't hang so I believe these are two separate issues. We do see the warnings on the mail AB too.

the main error was that he hang up and sent warnings that never came out and failed. now no workers are hanging but the warnings are still present ...

Last comment is that oe-selftest isn't hanging, therefore resolving the bug.

the problem is solved or-self test isn't hanging, therefore resolving the bug.
