[OpenSIPS-Users] Opensips 2.4.8 SEGFAULT

[James]

I made a little more progress. This is what I have now.

Message: Process 18626 (opensips) of user 993 dumped core.

I am using force_send_socket(udp:1.2.3.4:5060) with mhomed=1. Would this be an issue?

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:

I am running Centos 8. 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 -P /run/opensips/opensips.pid -f /etc/opensips/opensips.cfg -m 20480 -M 5120 -w /etc/opensips/dump
What am I missing in order to get a gdb core dump?

Thanks,
