Maybe best to track downstream unless we've identified it as an upstream bug.

BTW if you can provide me with all "SSLProtocol" statements in your config
that'd be useful.

Better to file bugs against Fedora bugzilla in the first instance.  There was a
bug in early Fedora 29 mod_ssl 2.4.37 packages which would manifest as a crash
during fork. Can you check "rpm -q mod_ssl" gives mod_ssl-2.4.37-5?
