<p>If you use the repo listed at <a href="http://deb.kamailio.org/" target="_blank">http://deb.kamailio.org/</a>
, then it should be 5.2.5, and there is also option to install 5.2
branch debs built nightly.</p>
<p>Cheers,<br>

<p>Hello,</p>
<p>that log message is irrelevant for actual crash. Did you
get core files? Or other log messages before the one you
pasted?</p>
<p>You should upgrade first to latest 5.2.x, either 5.2.5 or
latest branch 5.2.</p>
<p>Cheers,<br>
Daniel<br>
