<div dir="ltr">Hi, I'm running a instance of OpenSIPS (just
signalling no RTP on this machine) on a DigitalOcean VM, it was
running fine for a while and it does not process lots of CPS
(4-5 max) and today I was getting complaints of dropped calls, I
checked the logs and I saw lots of
WARNING:core:utimer_ticker: utimer task <tm-utimer>
already scheduled for 3956760 ms (now 3956860 ms), it may
overlap
<div>and
WARNING:core:handle_timer_<wbr>job: utimer job <tm-utimer>
has a 30000 us delay in execution
</div>
<div>I had 4 children and I upped it to 15, I think it helped
but not completely solved the problem.
When running top I see all of the sudden a few opensips
processes jumping to 100% and the idle resources slowly going
down sometimes even to 0% then it recovers, I haven't changed
anything in my cfg file lately and the traffic has not
increased etc.
Is there anyway to see in the logs whats taking so much
resources? I'm also wondering if its can be a DigitalOcean
issue where other users on the same Hyperviser are using very
high resources and its stealing my resources.</div>
<div>
</div>
<div>thank you</div>
