Hi! Yes, from the source on debian, I build deb package. (I did some minor changes to the source, but the problem happens also without my changes) 16 children on 4 cores.
What do you suggest to reduce it to 4? It runs on 2.6.32 on VMware ESX. I'm also trying now sleep(0) instead of sched_yield(). -- Best Regards, Alex Massover VoIP R&D TL Jajah Inc. > -----Original Message----- > From: users-boun...@lists.opensips.org [mailto:users- > boun...@lists.opensips.org] On Behalf Of Andrei Dragus > Sent: Wednesday, January 20, 2010 1:05 PM > To: OpenSIPS users mailling list > Subject: Re: [OpenSIPS-Users] sched_yield() > > Hi Alex, > > Are you building OpenSIPS from source? > How many processes do you have and on how many cores? > > > Alex Massover wrote: > > > > Hello! > > > > I'm facing a strange problem, sometimes under a stress OpenSIPS > > "locks" - load average jumps, SIP processing delays, opensips msg > > queue fills with a lot of sip messages, opensips processes start to > > comsume a lot of CPU. > > > > And strace shows: > > > > sched_yield() > > > > sched_yield() > > > > sched_yield() > > > > sched_yield() > > > > .... > > > > for all processes. > > > > If I stop the stress - after a while (not immediately) - it unlocks, > > also suddenly, I can see in top that all opensips processes stop to > > consume CPU. > > > > What can it be?
