[Freeswitch-users] Freeswitch 1.4.15 and a sudden jump in CPU usage

Wed Feb 11 21:58:30 MSK 2015

Hi Tristan,

Do you see a sudden jump or just more CPU usage?

In my case, everything is good for a few days with less than %10 CPU usage,
then there is a sudden jump to ~%98 CPU usage and it doesn't come down
until a restart. After restart, it's good again with the same load.

Thanks,
Ali Pey
