[SR-Users] Kamailio stops accepting calls for few seconds after 80 CPS.

[Aqs Younas]

Greeting list.

I am doing the load test of Kamailio with SIPp using most basic
script(kamailio.cfg) with logging level set to minimum to dispatch requests
to SIPp UAS.

This is my dispatcher code snippet.

        $avp(quality) = "1";
        ds_select_dst("$avp(quality)", "4");
        route(RELAY);

At 70 CPS calls work fine. But if I increase CPS to 80, Kamailio stops
accepting calls for few seconds and comes to life after being idle for some
time.

100 CPS for sip proxy is not hot cake.

Also, I see in http://www.kamailio.org/docs/openser-performance-tests/
tests were made with -l27 and -m7000 which looks wronged to me.

./sipp -sf uac_inv.xml
<http://www.kamailio.org/docs/openser-performance-tests/data/uac_inv.xml>
-rsa 192.168.2.102:5060 192.168.2.102:5070 -m 200000 -r 7000 -d 1 -l 27

There must be something wrong in my configuration since this cps is very
low.

Any suggestion is much appreciated.
