Apache dies at midnight

[Hoth]

Ever since I upgraded to Kubuntu 18.10, Apache has been dying every night at midnight. Any ideas?

A scheduled task going wrong?

Perhaps, but I haven't intentionally scheduled any.

I figured out the log location, and the error.log has a practically infinite list of errors every second today that all look like these two:
[Sat Mar 23 00:11:01.239615 2019] [core:notice] [pid 10880] AH00051: child pid 1572 exit signal Segmentation fault (11), possible coredump in /etc/apache2
[Sat Mar 23 00:11:01.239626 2019] [core:error] [pid 10880] AH00546: no record of generation 0 of exiting child 1572

Except for the first two lines of the log, which were 28 seconds after midnight and differ slightly:
[Sat Mar 23 00:00:28.794785 2019] [mpm_prefork:notice] [pid 10880] AH00163: Apache/2.4.34 (Ubuntu) configured -- resuming normal operations
[Sat Mar 23 00:00:28.794826 2019] [core:notice] [pid 10880] AH00094: Command line: '/usr/sbin/apache2'

Yesterday's log looks the same except it started 16 seconds after midnight.

But as far as I can make out, all those errors mean is "oops, I died, I don't know why." The fact that they repeat forever is more suggestive perhaps.

I would try reinstalling it. Maybe the upgrade messed something up.

You might want to go through your cron and anacron files to see what is running at midnight
