asterisk users - Oct 2009 - "got stuck at 150 calls, above that not working in stress test"

Hi All,

I have a problem, when I was doing a performance testing using an asterisk
server: Quadcore processor, 4GB RAM, CentOS5.2, after 150-151 calls all the
other calls are giving busy, I tried to do ulimit related stuff, like
increasing the soft and hard limits to 100000 but no luck, Any ideas or
views are really appreciated. Also I even changed the call limit to 500, but
stills it can handle only 150 total.

Thanks for your help.

Regards
Sandesh.

What do you mean it handles only 150?

What happens when you get above that number?

I regularly have more than that active on a machine.

Hi Matt,

When I get can more that 150 calls, i get a busy signal (Congestion) for the
calls above 150 - says "your call cannot be completed now", its
allowing
only 150 calls....Is there any thing related to field descriptors from linux
point of view that I need to increase inorder to increase the call
capacity.....

Thanks
Sandesh

I am using the command:
./sipp -sn uac -d 2000000 -s  <repective context pattern> <IP
Address> -l
200

Its 10 calls per second and 200 concurrent calls, similarly I used 2 ssh
sessions each sending 100 concurrent calls. But this was limiting to only
150 calls.

Thanks
