Hi Guys,

We are running kamailio 4.4.6 on debian 8 and not had any issues, however we did suffer a segfault and a core was generated;

May 25 09:17:06 Kam-HA-1 /usr/sbin/kamailio[9560]: ALERT: <core> [main.c:740]: handle_sigs(): child process 9575 exited by a signal 11

May 25 09:17:06 Kam-HA-1 /usr/sbin/kamailio[9560]: ALERT: <core> [main.c:743]: handle_sigs(): core was generated

May 25 09:17:06 Kam-HA-1 /usr/sbin/kamailio[9560]: INFO: <core> [main.c:755]: handle_sigs(): terminating due to SIGCHLD

Running gdb on the core file generated returns this output;

done.

Is this  of any help? Could someone advise what next steps might be?

Should we be looking to upgrade or is there a way to get more detail out of the core dump?

Many Thanks
