For a shorter version of memory status you can set memory_summary=2 or 3:<br>
<br>
<a href="http://www.kamailio.org/dokuwiki/doku.php/core-cookbook:3.0.x#mem_summary" target="_blank">http://www.kamailio.org/dokuwiki/doku.php/core-cookbook:3.0.x#mem_summary</a><br>
<br>
This will show quickly if there is a leak.<br>

Hello<br>
<br>
Can you give us more information on the modules you are loading/ your specific config ?<br>
<br>

Also, is it shared memory or private memory? If you have a dump of the memory distribution, can you spot anything out of the ordinary. As a tip look for functions in the ending part of the dump that repeat for multiple times. The lower offset is usually alloc'ed during module initialization so any big leak will happen at higher offsets (I don't know if this is the rule but this is what I observed).<br>
<br>
Have you tried increasing the memory pool?<br>
<br>
Cheers<br>
Marius<br>

Subject: [SR-Users] Memory leak<br>
<br>
Hello,<br>
<br>
We use Kamailio as a stateless load balancer.<br>
It runs on a VM, with 512 MB RAM, and it seems to have some kind of memory leak.<br>
The kamailio processes consume all available memory, until Kamailio crashes and restart.<br>
This occurs about once a day.<br>
Since it's stateless, and the restart is very fast, it's not a big deal, but I'd like to fix it.<br>
The strange thing is that I updated kamailio from 1.5.3 to 3.0.3 and the problem still ocurrs.<br>
I followed the instructions on <a href="http://www.kamailio.org/dokuwiki/doku.php/troubleshooting:memory" target="_blank">http://www.kamailio.org/dokuwiki/doku.php/troubleshooting:memory</a> in order to determine the cause, and stopped the traffic on the proxy. The allocated memory were not freed, after 1 hour the amount of free memory is still the same.<br>
Anybody has an ideia about what's happening, or how can I debug it?<br>
<br>
Thank you!<br>
<br>
Santiago Soares<br>
