<p class="MsoNormal" style="margin-bottom:12.0pt">Hello,<br>
<br>
can you reproduce it every time you run those commands? Or is it happening from time to time?<br>
<br>
If you can reproduce, set debug=3 and send all the logs to me. Also, it would be good to set 'ulimit -c unlimited' before starting kamailio to get a coredump which would be easier to troubleshoot.<br>
<br>
Cheers,<br>
