Hello,
is the attached backtrace from 5.8.4?
If you get many core dump files at the same time, attach the full backtrace for each of them, because usually one is revealing the reason of crash and the others are just side effects, but all need to be investigated in order to see which one is important for troubleshooting.
Some other details would be useful:
- what is the operating system you run? - is it a dedicated server, or some virtualization system (docker/kubernetes, virtual machine, ...)? - is it under high load when it happens, or some resources not available (e.g., database backend)? - can you list the modules that are loaded in kamailio config? Any with custom code, or all from stock kamailio repo?
Cheers, Daniel

Hi all
I have a setup of several proxies behind a load balancer and all of them have several coredumps every day. I've tried versions 5.3, 5.5 and 5.8 and all of them crash
I didn't have dbgsym packages installed but now I've built a 5.8.4 version in one of them and can gdb the coredumps. Can't see anything particular and I'm wondering if I'm doing anything wrong.
I'm descompressing the coredump with lz4cat. Sometimes I see that the system generates 3 coredumps at the same time. I've tried running gdb in one of them and exec "bt full"
I usually see "can't access memory" in some of them but inb others I don't see anything relevant.
I'm attaching one coredump. I don't even know if I'm doing it properly. Could you please guide me to how to debug what's going on?
thanks
