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

[Aaron Hamstra]

I do not recall if pike is enabled by default in the base config file or not, but you may be running into it blocking you.


Check to see if WITH_ANTIFLOOD is defined.  If it is and you want it you will need to adjust your pike modparams.  If it is enabled, and you do not needed remove the define.


If it is not enabled, it must be something else completely.

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<http://192.168.2.102:5060> 192.168.2.102:5070<http://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.

kamailio -version

Any suggestion is much appreciated.
