Hello! I am having an issue with opensips crashing. I have reviewed the guide on how to generate a core dump. My current problem is when I try to use gdb.
Here is what I am doing: gdb /usr/sbin/opensips core.opensips.993.b6ac8a71177a49cd8238e22ba265c6e9.16129.1594410164000000.lz4 GNU gdb (GDB) Red Hat Enterprise Linux 8.2-11.el8 Copyright (C) 2018 Free Software Foundation, Inc.

I installed opensips using the RPM from the opensips download site. The dump file is generated from systemd. I added the -w flag the service to put the dump file in the opensips directory but that did not change the location of the dump file. Here is the information from the crash in the logs. /usr/sbin/opensips[16129]: CRITICAL:core:sig_usr: segfault in process pid: 16129, id: 7 kernel: opensips[16129]: segfault at 0 ip 00000000004c4363 sp 00007ffcdf449470 error 6 in opensips[400000+212000] kernel: Code: c4 28 5b 5d 41 5c 41 5d 41 5e 41 5f c3 66 2e 0f 1f 84 00 00 00 00 00 48 c1 e8 03 89 c2 e9 8c fb ff ff 0f 1f 44 00 00 48 89 c2 <48> 89 37 48 c1 ea 03 48 c1 e2 04 48 01 ea 48 8b 4a 58 48 83 e9 01 systemd[1]: Started Process Core Dump (PID 16147/UID 0).

Thanks, James
