• A related mod_wsgi issue: apache2+mod_wsgi (python3) stop answer at random time GrahamDumpleton/mod_wsgi#458
• A related Debian issue: https://www.mail-archive.com/debian-bugs-dist@lists.debian.org/msg1911940.html

Neither has a solution/fix though.

I'm afraid there's not much we can do here without a clear reproducer, said reproducer should also target a newer version of Python as 3.7 no longer receives updates (not even security updates from us) and 3.7.3 is not even the most recent bug fix release for 3.7.

Also note that the problem can be anywhere in the stack, this may just as easily be caused by unexpected behaviour from Apache or mod_wsgi (or the interaction between the 3 components).

Can you reproduce the issue with Python 3.11 or later?
