Is Kamailio running in a hypervised environment? If so, I've seen async
workers cause high load at runtime, don't recall boot time.

Hello,
the async task workers are in recvfom(), which should not increase any
load.
Do you have any chance to test on another os/version? Maybe on centos 7
and see if it is the same case?
Cheers,
Daniel

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!
