This is a nasty bug because if for example a SSL certificate is replaced inside a vhost configuration, then older child processes will still serve the older certificate, resulting in certificate errors. Please check out PR 63169. Apache fixed this bug in 2.4.49, but the bugfix is still not included in the Ubuntu repository. Since this bug is pretty frustrating, I was wondering if this particular bugfix can be patched in Ubuntu's version of the apache2 package.

Hi Mike,
thanks for your report, at a first glimpse the case looks valid and
doable, therefore I have converted this into a proper bug [1] to be
tracked.
You could help the team to have a look by providing steps to recreate
the situation via an update on that bug.
