Hi,

We've just hit the same crash again, but on a different server for a
different client of ours. This time it was an upgrade from Wheezy to
Jessie, but the MPM is still worker.

This time in particular we hit the crash during the phpmyadmin security
upgrade recently. If I read the phpmyadmin maintscripts correctly,
Apache is reloaded once automatically by the apache2-maintscript-helper
when apache2_invoke is called to enable/disable its configuration file,
and once by the phpmyadmin maintscript itself via invoke-rc.d.

Best regards,
Chris
