Hello, I am experiencing the following problem: my dispatcher module is losing many calls when the scenario for balancing is about 175 CPS or more. Is there a limit that the module can do? Where do I find this information? Att., -- Rodrigo M. (37) 9132-4539 (34) 9889-3069

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: http://blog.csrpswitch.com/tuning-kamailio-for-high-throughput-and-performa… -- Alex -- Alex Balashov | Principal | Evariste Systems LLC Tel: +1-706-510-6800 / +1-800-250-5920 (toll-free) Web: http://www.evaristesys.com/, http://www.csrpswitch.com/

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. Regards., Rodrigo M. On Wed, Mar 8, 2017 at 2:34 PM, Alex Balashov <abalashov(a)evaristesys.com> wrote:

Hello, do you write log messages from config file when processing sip messages? Cheers, Daniel On 09/03/2017 19:22, Rodrigo Moreira wrote:

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? [image: Inline image 1] Thank you. Regards. Rodrigo M. On Thu, Mar 9, 2017 at 5:31 PM, Daniel-Constantin Mierla <miconda(a)gmail.com> wrote:

Hello everyone, I found the problem. It was just memory shortage, I allocated more memory from 64 MB to 256 and it worked. Thank you all. On Fri, Mar 10, 2017 at 6:09 PM, Rodrigo Moreira < rodrigo.moreira206(a)gmail.com> wrote:

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 On 10/03/2017 22:09, Rodrigo Moreira wrote:
