Not to nag or anything, but any sort of timescale on this? I'd happily
help out, but having read through the process I'm not actually sure what
needs doing...

Yes, this can be backported to Focal. It will need somebody affected to
commit to doing the necessary QA after the update is prepared (without
that QA, we won't be able to land the update).
The process is documented at

The crash is bizarre. I have plenty of other hosts that are making use
of mod_perl with no issues at all. It can't be (directly) application
specific, as it's crashing before it even gets to running any of the
perl. If I uninstall mariadb (required for this application), it starts
working again.
Hello and thanks for all the debugging work here. I agree with your
