Package: apache2-bin
Version: 2.4.66-1~deb12u1
I’m getting segmentation faults in the error_log, and, after
some try and error, have been able to acquire a core dump.
Unfortunately, the system doesn’t have access to dbgsyms or
debuginfod, and gdb doesn’t like it when the versions differ
so I can’t gdb it on my local system, but here’s what info
I already have:

ELF object binary architecture: AMD x86-64
└─┤ snap ├─────────────────────────────────────────────────────────────┘
Does this help? If not, I can try to set up a chroot with
matching binary packages inside and try to get a full bt
for all threads, with debuginfod.
Is this possibly related to the zombie processes bug that was just fixed
https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=1125713 ? Even if the
system doesn’t have PHP as FastCGI, the source of those zombies is AIUI
that the Apache2 processes die, which is what I’m observing, multiple
times a day on that system.
Should I perhaps backport 2.4.66-5 to bookworm locally and see whether
those segfaults go away? Given it already has -1, the changes should be
sufficiently minimal…
Thanks in advance,
//Thorsten
