Hi Daniel,

The child process is terminated by signal 11 (SIGSEGV).

Dec  8 16:41:25  /sbin/kamailio[12000]: ALERT: <core> [main.c:777]: handle_sigs(): child process 12003 exited by a signal 11

Dec  8 16:41:25  /sbin/kamailio[12000]: ALERT: <core> [main.c:780]: handle_sigs(): core was generated

Dec  8 16:41:25  /sbin/kamailio[12000]: INFO: <core> [main.c:792]: handle_sigs(): INFO: terminating due to SIGCHLD

Maybe not relevant but the process 12003 that is killed has last logged a line to kamailio.log like 6000 lines above the SIGSEGV:

Dec  8 16:40:46 /sbin/kamailio[12003]: ERROR: pv [pv_core.c:304]: pv_get_ruri_attr(): failed to parse the R-URI

Have not yet tried the latest branch, will do so tomorrow.

Kind regards

Timo Klecker

Hi Daniel,

I tried to increase shared memory by setting a parameter in kamctlrc:

STARTOPTIONS="-m 64"

When recreating the crash I counted pv_get_ruri_attr in the logfile just to see if the shared memory changed anything:

> grep pv_get_ruri_attr /var/log/kamailio.log | wc -l

75472 with default settings

75436 with shared memory set to 64

75440 with shared memory set to 256

But in top I saw a massive increase in memory usage.

I don’t know if this is any helpful for you.

It might be that the OS kills the process due to too much memory usage. Can you check again the logs and see what was the signal that killed the process?

Btw, have you tried with latest git branch, after I did the patch for fixing empty username?

Cheers,
Daniel
