[Freeswitch-users] What FS is doing when idle?

that's not a problem, is how FS works.
That load on the CPU when idle is actually not important. Is just the
minimum, like in a carburettor.
If you put it under load, you will see that there will need some
serious load (many calls) to have it ramp up the cpu usage.
