[OpenSIPS-Users] OpenSIPS crashing but gdb not recognising core dump symbols

[Kingsley Tart]

Hi,

OpenSIPS 3.1.5 is crashing a lot on Debian 10.

I'm trying to use gdp to get a trace from a core dump but it isn't
loading the symbols.

I installed opensips-dbg, restarted opensips, managed to crash it again
and then ran gdb to examine the core dump, but it still didn't have the
symbols.

Here are the installed OpenSIPS packages:

root at ipx-a:/tmp# apt list --installed | grep opensips

WARNING: apt does not have a stable CLI interface. Use with caution in
scripts.

This is what gdp said:

root at ipx-a:/tmp# gdb . core.opensips.107.1635172491.18078

How can I fix this to get a proper trace?
