<p>Hello,</p>
<p>kamailio 4.4 is no longer maintained. Upgrade to latest kamailio
5.2.x and try again. The backtrace indicates the race in tm wait
handler that was fixed a while ago, but likely after 4.4 series.</p>
<p>If you still get the issue with 5.2.x, then send the new
backtrace you get with that version.</p>
<p>Cheers,<br>
Daniel<br>

<div>Hi folks,<br>
<br>
I am doing some experiments with Kamailio and Cgrates. To be
precise I am testing evapi module. When in testing
environment I do not have any problem. After redirecting
some production traffic to this kamailio, It crashes in at
random times (few minutes to 20). I didn't find any pattern
here.<br>
<br>
CGRateS doesn't write anything in logs.<br>
<br>
I'm on the last 4.4 Kamailio (compiled recently). CGRateS is
on the last version.</div>
<div><br>
</div>
<div>Can you please point to how to continue with debugging?</div>
<div><br>
</div>
<div>Thanks</div>
