If you get the shm used size increasing, run following commands:<br>
<br>
kamcmd cfg.set_now_int core memlog 1<br>
kamcmd corex.shm_summary<br>
<br>
Do it after some time of running, when you see that the increase has
happened.<br>
<br>
Then take the logs from syslog related to shm summary and send them
over here.<br>
<br>
On the other hand, I saw recently some article about latency spikes
for tcp:<br>
<br>
- <a class="moz-txt-link-freetext" href="https://http2.cloudflare.com/the-story-of-one-latency-spike/">https://http2.cloudflare.com/the-story-of-one-latency-spike/</a><br>
<br>
It is about http, but actually relates to tcp setting of os. Maybe
you can verify your values in OS.<br>
<br>

<div>Sometimes kamailio is receiving the

tcp) but the message is not handled nor
relayed.</div>
<div>After a certain amount of time
everything works fine.</div>

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