[Freeswitch-users] Does freeswitch forks his processes?

[Vladislav Ivanov]

Hey guys,

It is true, I haven't ran it as root, I fixed it.
But I still have issues with passing more than 50cps, same is happening...
4 cores CPU - CPU is good, 80% idle, load average: 0.81, 0.98
This at 25 cps (I bridge the call, so cps*2)
Then I add 5 cps more:
load average: 1061.40, 333.52
And all OS start's lagging as hell, and i'm unable to find issue, have no
idea what is happening...

My settings:

Anything I'm missing? Really strange that CPU drops like that...
