<p>Hello,</p>
<p>can you install the package with kamailio debugging symbols? Then
take again the kamctl trap with two async workers, it should
contain more details about what pieces of code run.<br>
</p>
<p>The package should be named like kamailio-dbg...</p>
<p>Besides that, can you also do a 'top' and see what kamailio
processes (their PIDs) eat a lot of cpu?</p>
<p>Cheers,<br>
Daniel<br>

<div>Attached are two files. One for 2 Async Task Workers and
one for 8 Workers. The second one was stuck and did not
complete.</div>

</div>
<div>I should point out that the virtual machine has 2 CPU
cores. Load average value was stable with 2 workers and was
slowly increasing after adding more workers. * workers caused
it to increase very fast.</div>

<p>Hello,</p>
<p>if you can, it would be interesting to get the backtrace
and see what was causing the load.</p>
<p>Iirc, the Async Task Worker should wait on read on an
internal socket, so it should be no CPU used when nothing
is transmitted to this type of workers.</p>
<p>Cheers,<br>

<div>I run <i>kamctl trap</i> command but the procedure
got stuck. Last line in the generated file contained
"---start 12767 -----". 12767 was an Async Task
Worker. Since I don't need them I just removed related
configuration. It must be left after the testing. This
solved the problem.</div>
<div><br>
</div>
<div>Please let me know if you are still interested in
what was going on and if I should restore the
configuration and run <i>kamctl trap</i> again.</div>

</div>
<div>Thank you very much!</div>

<p>Hello,</p>
<p>install gdb and, when the load is high, run:</p>
<p>kamctl trap</p>
<p>It write a file with what kamailio was doing at
that moment. Send it over here on mailing list or
make it available for download somewhere. We can
look at it and guide further about what can be
done.</p>
<p>Cheers,<br>

I'm running Kamailio version 5.3.3 on a CentOS
6. I started noticing that "load average" value
increases rapidly with the start of Kamailio:
<blockquote style="margin:0px 0px 0px
40px;border:none;padding:0px">
<div># uptime</div>
<div>17:47:52 up 4 days, 17:47, 3 users,
load average: 7.02, 7.01, 6.02</div>
<div><br>
</div>
</blockquote>
It will start to decrease immediately after
Kamailio is stopped.
<div><br>
</div>
<div>Does anyone know what could cause this and
how to troubleshoot it?</div>
<div><br>
</div>
<div>Thank you!</div>
