What is the exact version are you using (kamailio -v)?

How many open connections do you expect to have at same time?

Or get:

kamcmd core.tcp_info

Cheers,
Daniel

If you get the shm used size increasing, run following commands:

kamcmd cfg.set_now_int core memlog 1
kamcmd corex.shm_summary

Do it after some time of running, when you see that the increase has happened.

Then take the logs from syslog related to shm summary and send them over here.

On the other hand, I saw recently some article about latency spikes for tcp:

  - https://http2.cloudflare.com/the-story-of-one-latency-spike/

It is about http, but actually relates to tcp setting of os. Maybe you can verify your values in OS.

Cheers,
Daniel

Are you doing the http requests for all sip requests? How many rtimer processes do you have consuming from mqueue?

What do you mean by "all tcp workers were busy"? They used lot of CPU?

I have a mqueue with rtimer to do asynchronous http request.

I have seen also sometimes that all tcp worker were busy even on a test server with 4 clients.

Had someone found the solution or faced similar issue ?

Sometimes kamailio is receiving the message (check with wireshark, logs in tcp) but the message is not handled nor relayed.
After a certain amount of time everything works fine.

I will do what as has been advised : enabling pike & check with gdb when it appears.
