Yes, this looks pretty much like what I'm seeing (assuming Glyph's speculation it could be related to python2.7 is wrong, as this is on python3; but I'm going with openssl as the central culprit). > Further running the server with valgrind might show something > related, if the crash happens there too. Since this appears to be a known problem, there's reason to hope it will go away when moving to bullseye, disabling https upgrading made the crashes disappear, and I can live with http for this particular service, I think at this point I'm willing to risk something that feels rather exploitable for another few weeks. These considerations would change if others were seriously concerned; given the twisted ticket has indications on how to trigger the bug outside of production, I might try to organise a windows client to trigger it on a development system. Thanks, Markus
