Re: [SR-Users] Dispatcher Module - Hava limit?

Hello,

my question was to figure out if you have many xlog() (or similar) calls in kamailio.cfg, because extensive logging can slow down if syslog daemon is synchronous.

Cheers, Daniel

Hi Daniel-Constantin,

As follows in the attached image this is the output of the command systemctl status kamailio.service.

One important thing, the machine that hosts my Kamailio service is using high storage almost 100%, is this the problem of so many errors when I try to make more than 200CPS?

Thank you.

Regards. Rodrigo M.

Thank you Alex Balashov!

I read the link that suggested, very good the issue of child
processes fit as described. I have a machine with the
carrierroute module, it can handle 150 CPS without fail, when I
increase this number for eg 175, there are countless losses. I
have increased the shared memory, but I still can not understand
the grinding of so many losses. Do you have any suggestions for
anything you can check?

I know the problem is not the network channel because it
currently has 40Mbps.

    The dispatcher has no such limits. Also, how did you
    determine that the
    dispatcher module is the essence of the "loss" that you are
    seeing? It
    is most likely happening in a more general context:
