Hi,
I am doing load testing with of Kamailio. I have sipp (version 3.3) as the
load generator,Kamailio(4.2.7) as Load Balancer and Freeswitch (1.6.5) as
Gateways.
I am using the following command to generate load
./sipp -sf uac.xml -d 2000 -m 4000 -l 1000 -r 200 -trace_stat -i SIPP_IP
-p 15060 --trace_err -trace_error_codes -trace_calldebug -trace_screen
KAM_IP
When the rate of generation is below 80 (-r 80), Kamailio behaves fine.But
if we go beyond 80, Kamailio starts sending "500 Service Unavailable"

I am not seeing any errors in Kamailio Logs.
Any pointers on how to get it to serve more calls/sec
