<p class="MsoNormal" style="margin-bottom:12.0pt">Hello,<br>
<br>
got dragged by some other tasks for a while...<br>
<br>
Can you list here all your loaded modules? Also, are you having event routes in your config?<br>
<br>
At this moment it looks like either a buffer overflow somewhere or a free of an shared memory element without detaching from timer. I will need more details to narrow it down.<br>
<br>
Cheers,<br>

<p class="MsoNormal">Kamailio runs on Ubuntu trusty. The interesting thing that we run Kamailio 4.2.3 in an other environment (on Debian Squeeze) and it works perfect, no crashes. The main difference is that in Debian environment we have less number of users
and the firewall is not so strength. But the configuration and the source is the same for both.<o:p></o:p></p>
<p class="MsoNormal"> <o:p></o:p></p>
<p class="MsoNormal">Please help us to solve this problem. Thanks. <o:p></o:p></p>
