SBB <samorders at gmail.com> has reassigned Bugzilla Automation
<bugzilla at FreeBSD.org>'s request for maintainer-feedback to apache at FreeBSD.org:
Bug 204793: www/mod_python35: Fatal Python error: PyEval_SaveThread: NULL
tstate
https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=204793



--- Description ---
Not sure what's needed here but I've included everything I can think of. Let me
know if I've missed anything or more info is needed.

Problem: Apache runs for about a day but then crashes with this error in the
error log (even with little to no use). I have 2 httpd core dumps if that would
help.

Found a similar issue on http://bugs.python.org/ but the python devs indicate
it's not a problem with python but the 3rd party program. Not sure if it
applies to this but thought I'd mention: http://bugs.python.org/issue16749
