[Freeswitch-users] Freeswitch Performance Testing

[Michael Jerris]

You wil get that error if you hit a system thread limit or run out of  
memory.  We generally recommend using a 64 bit cpu and os and the  
settings detailed:

http://wiki.freeswitch.org/wiki/Performance_testing_and_configurations

Also, not that the default config has sessions per second limited at 30.
