I'm running probably one of the most stripped down FreeSWITCH configs you can run ... Sofia only, bypass media, with a custom C routing module that uses libpq directly... the problem happens at somewhere around 50 to 100 CPS, system % goes thru the roof, and its not IO.. loglevel 0... etc... now its also worth mentioning that on 6.2 the number of context switches for similar amounts of calls on the same physical hardware seems to be double vs something like cent5 or deb6.... we're currently trying to get people to submit reports from oprofile so we can isolate the issue... if it were just me, I would chalk it up to something specific on the installation, but , the number of reporters with similar observations is something to take notice of...

At least on one of our boxes, running on CentOS 6.2 ends up with one FS thread stuck at full CPU. We haven’t noticed anything getting worse as more load gets added. My feeling is that perhaps there’s some sleep or something that is now much more granular with a tickless kernel so now it’s waking up all the time, instead of 1000Hz. But several folks have told me tickles ain’t the issue. ****

At any rate, machines are big and profitable, so losing a single core to a runaway thread isn’t a huge priority for me :\.****

Is anyone having the same problems with RedHat or is this CentOS specific? ****

Centos5 worked well for me, Centos6 worked for crap... I went to debian 6 (squeeze) and problems went a way... using the latest stable on the debian6 line installing from the netinstall (non-free variant as I have hardware thats not supported under the main netinstall iso) and then installing freeswitch via the instructions on the wiki and no problems so far****
Same here. We're CentOS 5 here and Debian Squeezy for new boxes.
