hi,

"top" shows the freeswitch process with up to 25-30% CPU usage (5 channels in a conference, 1x Speex, 1x GSM, 2xPCMA, 1xPCMU), while total userland usage is shown at 0.1%. Also mpstat shows almost 100% idle. Is it a bug in the kernel? or any other ideas?

Intel Atom N570, 2 physical cores with hyperthreading, /proc/cpuinfo shows 4 CPU's.

Debian 7.4 i386

3.2.0-4-686-pae #1 SMP Debian 3.2.54-2 i686 GNU/Linux

FreeSWITCH 1.2.22 from debs
