Hello again,
I attached a new file.
The interesting part is that Kamailio does not load the CPU at all.
/Top/ shows it at the bottom. Only the "load average" value gets
increased.
Thank you!

Hello,
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.
The package should be named like kamailio-dbg...
Besides that, can you also do a 'top' and see what kamailio
processes (their PIDs) eat a lot of cpu?
Cheers,
Daniel

Hello,
Attached are two files. One for 2 Async Task Workers and one for
8 Workers. The second one was stuck and did not complete.
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.
Thank you!

Hello,
if you can, it would be interesting to get the backtrace and
see what was causing the load.
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.
Cheers,
Daniel

Hello Daniel,
Thank you for your response.
I run /kamctl trap/ 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.
Please let me know if you are still interested in what was
going on and if I should restore the configuration and
run /kamctl trap/ again.
Thank you very much!

Hello,
install gdb and, when the load is high, run:
kamctl trap
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.
Cheers,
Daniel

Hello everyone!
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:
# uptime
17:47:52 up 4 days, 17:47, 3 users, load average:
7.02, 7.01, 6.02
It will start to decrease immediately after Kamailio is
stopped.
Does anyone know what could cause this and how to
troubleshoot it?
Thank you!
