Re: [Kamailio-Users] UDP packet loss

Hi, I am performing SIP to SIP performance testing using Kamailio proxy (UAC-Kamailio-UAC). After increasing the load to 300 calls/sec Kamailio begins dropping UDP packets. (250 cps works fine). CPU utilization and network bandwidth looks fine. I think the bottleneck is the Linux UDP buffer size of the proxy server. Here is the proxy server information:

$ uname -a Linux lab-linux01 2.6.24-19-server #1 SMP Wed Jun 18 14:44:47 UTC 2008 x86_64 GNU/Linux $ sudo sysctl -a | grep net.core.rmem_max net.core.rmem_max = 131071 The question is if I increase the linux UDP buffer size do I need to change any configuartion parameter (like MAX_RECV_BUFFER_SIZE) in Kamailio?
