<tt>Hi Pasan,<br>
<br>
Are you able to run (just for testing purposes) opensips directly
on the host machine? I just trying to see if the difference will
impact.<br>
<br>
Regards,<br>

<div>Hi Bogdan,<br>
<div><br>
<div>Nice to here from you :) Thank for clarifying about
the warning. My delay times are only vary between <span>40000
us - <span>50000 us. I got 6 vCPUs allocated to my
kvm guest , host machine has 16 cores in total. I
wondered if these are related to guest CPU stealing
as I get 0.02% of max cpu steal value according our
monitoring graphs.<br>

That warning (harmless in 99% of the cases) reports
the delays between (a) triggering a timer job in timer
processes and (b) executing that timer job in a worker
process.<br clear="none">
<br clear="none">
If there is no load (worker processes are idle, no
busy with anything else), the reported delay may be
generated only by the interprocess communication
(passing the job from the triggering process to the
executing process via internal pipes).<br clear="none">
<br clear="none">
What are the values you typically observe ? maybe the
warning is jst about a slow context switching on your
server (btw, how many cores ?).<br clear="none">

<div>The servers doesn't process anything most
of the time. I'm wondering whats causing
these warnings. I tired script_trace and
enable debug level 5 and nothing explains
why it complains like this. It just pops out
in the log without any other related log
