Hello,<br>
<br>
reproduce the case with 'ulimit -c unlimited' executed in the
terminal before starting kamailio. You should get a corefile and
then get the output of 'bt full' in the gdb (gdb /path/to/kamailio
/path/to/corefile). Send the output here to investigate it.<br>
<br>
Cheers,<br>
Daniel<br>
