bunch of celery workers (loader*, lister*) indeed have a ConnectionResetError stacktrace (not necessarily the same):
As per our pair-programming yesterday, I think we reproduce this in production now (with the runner at least).

I confirm that I do not see ConnectionResetError: [Errno 104] Connection reset by peer and BrokenPipeError: [Errno 32] Broken pipe so far in the runner logs with kombu from git's master.
