<div>Hi,</div>
<div><br>
</div>
<div>We use kamailio as a router in our PBX server. The test
below causes significant decreasing of free shared memory and </div>
<div>many "out of memory" errors in kamailio log:</div>
<div><br>
</div>
<div>Preconditions: kamailio server with 256Mb of shared memory
allocated.</div>
<div><br>
</div>
<div>Test actions: run two load testing scripts at the same
time: </div>
<div> 1) 10000 register operations;</div>
<div> 2) 20000 calls (about 300 per sec);</div>
<div><br>
</div>
<div>Results: </div>
<div> 1) memory consumption in peak values:</div>
<div><span class="m_8476200490339429957gmail-Apple-tab-span" style="white-space:pre-wrap"> </span>
- shmem.free_size: 1.8Mb</div>
<div><span class="m_8476200490339429957gmail-Apple-tab-span" style="white-space:pre-wrap"> </span>

- tm module: 118Mb</div>
<div> 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><br>
</div>
<div>Is it normal behavior or it's possible to do something to
increase performance?</div>
<div><br>
</div>
<div>PS: the same behaviour occurs for various values of shared
memory defined at the start of kamailio server (128Mb, 256Mb,
512Mb etc.).</div>
<div><br>
</div>
<div>Thank you,</div>
<div>Andrey</div>
