This is during shut down clean up. Have you stopped kamailio
manually? If not, aave you got more than one core file? If not,
enable one core file per process.<br>

<div bgcolor="#FFFFFF" text="#000000"> Hello,<br>
<br>
do you get other error messages in syslog before the one
"CRITICAL: ..."?<br>
<br>
It is hard to say it is from something already known or
new. Right now there is an open issue for saving dialog
variables in database that was not yet sorted out. Another
one related to tm and memory manager, reported after
4.3.1, got a safety fix. Apart of these two, I don't
remember any active crash report for the moment.<br>
<br>
If you get it very often, then it should be easy to catch
and troubleshoot properly. Can you run it so it generates
a core file?<br>
<br>
The easiest way is to run it as root, with 'ulimit -c
unlimited' executed before starting kamailio.<br>
<br>
Can you share what operating system are you using and
exact version of kamailio (output of kamailio -v)?<br>
<br>
Cheers,<br>
Daniel
