<p>My understanding is that used memory goes back to normal after
the test, not something that stays high forever, so it doesn't
look at all with what you refer to.</p>

Andrey,
<div class="">Can you please run “kamcmd tm.stats” and check the
values. I have a similar problem and see clearly</div>
<div class="">a lot of transactions not being freed, eating up
memory and ending with out of memory messages in the log.</div>
<div class="">Have an open issue about it in the bug tracker.</div>

<div class="">Hi,</div>
<div class=""><br class="">
</div>
<div class="">We use kamailio as a router in our PBX
server. The test below causes significant
decreasing of free shared memory and </div>
<div class="">many "out of memory" errors in
kamailio log:</div>
<div class=""><br class="">
</div>
<div class="">Preconditions: kamailio server with
256Mb of shared memory allocated.</div>
<div class=""><br class="">
</div>
<div class="">Test actions: run two load testing
scripts at the same time: </div>
<div class=""> 1) 10000 register operations;</div>
<div class=""> 2) 20000 calls (about 300 per sec);</div>
<div class=""><br class="">
</div>
<div class="">Results: </div>
<div class=""> 1) memory consumption in peak
values:</div>
<div class=""><span class="gmail-Apple-tab-span" style="white-space:pre"> </span>
- shmem.free_size: 1.8Mb</div>
<div class=""><span class="gmail-Apple-tab-span" style="white-space:pre"> </span>
- core: 120Mb:</div>
<div class=""><span class="gmail-Apple-tab-span" style="white-space:pre"> </span>
- build_req_buf_from_sip_req: 12.5Mb</div>
<div class=""><span class="gmail-Apple-tab-span" style="white-space:pre"> </span>
- msg_lump_cloner: 23.6Mb</div>
<div class=""><span class="gmail-Apple-tab-span" style="white-space:pre"> </span>
- sip_msg_shm_clone: 84Mb</div>
<div class=""><span class="gmail-Apple-tab-span" style="white-space:pre"> </span>
- tm module: 118Mb</div>
<div class=""> 2) shmem.free_size parameter back
to normal after the test, so it could be concluded
that we don't have any memory leaks.</div>
<div class=""><br class="">
</div>
<div class="">Is it normal behavior or it's possible
to do something to increase performance?</div>
<div class=""><br class="">
</div>
<div class="">PS: the same behaviour occurs for
various values of shared memory defined at the
start of kamailio server (128Mb, 256Mb, 512Mb
etc.).</div>
<div class=""><br class="">
</div>
<div class="">Thank you,</div>
