[Freeswitch-users] FreeSWITCH 100% CPU utilization

[Örn Arnarson]

Thanks again.

I did another strace, which for some reason crashed my FreeSWITCH (whoops),
but after the restart, I'm seeing around 10% CPU utilization on that thread.

It seems that there was something odd going on with the main signalling
thread.

Regards,
Örn
