Hi Simon,

Maybe you have some apport service running on the machine, moving the core file.

Dear Bogdan,

we tried following https://opensips.org/Documentation/TroubleShooting-Crash and trying different things, and even though the syslog shows that the core file was dumped:

the core does not get generated, or at least not in the directory provided via options at runtime (-w /tmp). The issue is always repeatable (the daemon crashes after every finished call), if there are more active calls at the moment of the crash, whose calls remain active and proceed normally until termination (which again causes a crash). We also tried enabling debug mode, but in that case the process does not start successfully and runs into a timeout. In any case, any additional help or suggestion on how to successfully generate the core dump would be much appreciated, as we seem to have ran into a wall here...

Hi Simon,

Well, the log is very self explanatory:
Dec 7 15:59:47 sbc2 /usr/sbin/opensips[28488]: INFO:core:handle_sigs: child process 28495 exited by a signal 11 Dec  7 15:59:47 sbc2 /usr/sbin/opensips[28488]: INFO:core:handle_sigs: core was generated Dec  7 15:59:47 sbc2 /usr/sbin/opensips[28488]: INFO:core:handle_sigs: terminating due to SIGCHLD

Or shortly, you opensips just crashed :). So see https://opensips.org/Documentation/TroubleShooting-Crash for how to report further.

Hi

we are running opensips 3.4.2
on Ubuntu 22.04.3 LTS
and also use RTPengine Version: 10.5.0.0+0~mr10.5.0.0 git-master-74075f63

Opensips acts as SBC with RTP engine enabled.

Calls are working fine, however after each call is finished, bellow action happens.

We had same problem with opensips 3.2 and Ubuntu 20. So we did upgrade to latest stable release, and it is the same.

Is this opensips script configuration issue or a bug? And how could I fix it?

Thanks for all tips.

BR
Simon
