Hi Christoph,

I hope you can give a hint. Xymonserver (4.30-3.el9) is installed on an alma Linux Server an running fine. There is an output in /var/log/messages every 5 minutes which looks like this: "kernel: traps: svcstatus.cgi[3519701] general protection fault ip:411288 sp:7ffcbdd46878 error:0 in svcstatus.cgi[402000+23000]"
Any ideas where to start my investigations?
Just very generic ones:
Enable core dumps.
On the next GPF, investigate the core dump with gdb (The GNU Debugger), especially create a backtrace with "bt". Chances are that you find it somewhere under /var/crash/ or in /var/lib/xymon/ or /run/xymon/.
You might need additional debug symbols for getting a useful backtrace. They're either in debuginfo RPMs which need to be installed for analysis, too. (There's also the possibility that AlmaLinux offers an debuginfo server, see https://www.redhat.com/en/blog/how-debuginfod-project-evolved-2021, where a client can automatically download the required debuginfo based on build-ids, not packages.)
The less pure jump addresses and the more function names show up, the more useful is the backtrace for the developers (or yourself).
Either try to find the place in source code where the crash happens or send the backtrace to this list.
See https://fedoraproject.org/wiki/StackTraces for some more details. (I assume that most what applies to Fedora also applies to AlmaLinux.)
