I don't think that upgrade changed anything that actually caused the problem. But it is possible that the libssl upgrade triggered a restart of apache2 that somehow lead to the problem. > I tried to change the Mutex to: > Mutex sem default > and everything is fine now. The default mutex implementation has been changed in stretch (since 2.4.20-1) so this hopefully does not happen there anymore. But this is not something that I want to backport to jessie in a stable point release. Unless this affects a lot of people. So, people who encounter this may want to add a note to this bug report.
