[users@httpd] AH00051: child pid 3886730 exit signal Segmentation fault (11), possible coredump in /etc/httpd
Hi,
I'm using httpd-2.4.62 on fedora40 and noticed periodic errors related
to core dumps. Is this a potential bug? I see there are several similar
bug reports with previous versions but never a resolution.
[Wed Sep 25 11:07:16.786647 2024] [core:notice] [pid 1616:tid 1616]
AH00051: child pid 3886730 exit signal Segmentation fault (11), possible
coredump in /etc/httpd
Have there been other reports of this version having such problems?
Before I run memtest to see if it's a physical memory problem, I'm
hoping someone has some insight. I do see a handful of other similar
reports over the years, but none recently.
Is it possible a configuration change has caused this?
The gdb trace of the coredump is entirely too involved for me to spend
time tracing it.

I'm using event with php-fpm. Attached is the full list of modules
("httpd -M" on my fedora40 system). Hopefully the list accepts text
attachments.

What mpm are you using on that server? Can you share apachectl -M?

Hi, thanks for your help. Bug created here.
https://bz.apache.org/bugzilla/show_bug.cgi?id=69350
I can also provide a coredump (33MB).

Send the backtrace of all threads as an attachment or open a bug
report and attach it there.

I have the coredumps and could send the stack trace. Would this be
helpful? The output is voluminous.
The iDRAC isn't reporting any memory issues, so I believe this is
software related now. I also don't think it's a resource allocation
problem, as there's plenty of free memory.
What else can I do to troubleshoot this?

The crash symptom by iteslf doesn't mean very much without specific
