<p class="MsoNormal" style="margin-bottom:12.0pt">Hello,<br>
<br>
one thing to clarify. Are you running v4.2.3 from packages/tarballs or from branch 4.2?<br>
<br>
There was a fix to jsonrpc-s, already backported to branch 4.2 few weeks ago, but after release of 4.2.3.<br>
<br>
If you don't run from git branch, can you install from there (or from debian nighty builds)? It might be same issue, so it is better to check that before further troubleshooting.<br>
<br>
Cheers,<br>

<p class="MsoNormal" style="margin-bottom:12.0pt">Hello,<br>
<br>
I need the logs printed by kamailio before the crash, to see what was processing at that time. After crash is no information in the logs printed by itself why it crashed .<br>
<br>
The traces printed in syslog by the kernel are not easy to use for troubleshooting and I see the core was not generated to use gdb for a proper backtrace. Have you run 'ulimit -c unlimited'?<br>
<br>
Cheers,<br>
Daniel<o:p></o:p></p>

<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>
