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

Wed Feb 11 16:46:19 MSK 2015

we have add this option to grub and reboot one months ago. no help.

we have media-pass-through  option, and have more than 10 thousands
sessions. it works fine all day and the CPU will rise suddenly about
9:00 am every day.  i should restart the FS to recovery.
