Hello,

Someone has an idea?

Again, Kamailio stop processing SIP during more than 30s. Nothing print in the logs.

The processing back on when a script detect no answer and restart the service.

Regards,

Igor.

Hello,

I'm wondering if there's a best practise to dimension the number of child to setup?

I see, very often, Kamailio that stops to reply to SIP traffic for couple a seconds. This cause some calls drop if RE-INVITE are not processed for example.

So, I'm wondering if the issue is not due to a lack of child for processing the SIP traffic.

Thank you for your inputs.

Regards,

Igor.

You need to increase the number of child. What is current CPS?

Hard to say. Is there this kind of stats on Kamailio?

Are you using pike module or any kernel/iptable module for tracking sip traffic?

If you use statsc module you can get details about how many requests were received per specific interval of time.

Cheers, Daniel

4:16 p.m.

I'm using snmpstats and dialog.

IPTables is used but not with SIP tracking module.

But if I work on a Wireshark trace during a representative peak period (during ~12min), I have 30-40 INVITE/second ; 3 REGISTER/second and 7 OPTIONS/second.

Kamailio is running with 15 children actually.

Regards,

Igor.

The load is not big.

Is the SIP traffic over UDP?
