Package: libapache2-mpm-itk
Version: 2.4.7-04-1+b1
Severity: important

Dear Maintainer,

After installing the 2.4.51-1~deb11u1 security update the error log
starts to get flilled with lines like:
[core:notice] [pid 3115298] AH00052: child pid 3133160 exit signal
Segmentation fault (11)

Downgrading back to 2.4.48-3.1 made the errors disappear again.
Disabling mpm_itk on 2.4.51-1~deb11u1 also stops the errors.

The issue normally does not prevent pages from being loaded and they
are still assigned the correct uid/gid.

The problematic part lies in that it seems to cause issues with properly
closing the connections. This lead to mod_qos limits being hit in my
case, but I suspect it may also lead to hitting worker or thread pool
limits in other cases.
