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,

In a single rtimer, I am consuming the mqueue and calling a lua script.
(I have followed the example of twitter).
I have increase the number of tcp_children and I got issue for memory
allocation on allocations new tcp connection after a few hours.
Restart with SHMEM increased.
(but shame:used_size seems to increase)

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?

It seems to appear randomly.
I don't have database access (default config without db)
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.
