[SR-Users] Kamailio not responding in heavy load

[Henning Westerholt]

Hello,

I'd suggest have a look to the PostgreSQL database, like the processlist of the current running queries. You can also do some network tracing for the SQL queries that are used, or look to the slow query log (don't know how this is called in PostgreSQL).

Then start some optimization, e.g. use some caching or similar, to get better throughput.

Cheers,

Henning

Subject: [SR-Users] Kamailio not responding in heavy load

Hello all,

I'm using sqlops module to connect to postgres and get the routing of calls from postgresql database.

In order to troubleshoot issues in case they happened, I added each call details to Kamailio log.

In some cases, when there is heavy traffic load (around 100 cps), I don't find some calls in Kamailio log, knowing that I can find them on the switch log (switch sending the invite packets to Kamailio).

When checking the traces on these calls taken by the switch, it's clear that Kamailio is not responding to the invite packets sent by the switch. It could be because there are no available process to handle the call at this moment (I have set fork=14)

Is it possible to check if there are calls pending in the queue?

Regards,
