The trick is to set (in this order):<br>
memlog = 4<br>
memdump = 1<br>
<br>
This will do no logging at runtime, but it will log the mem dump
(at shutdown or at signal).<br>
<br>
Could you try that ?<br>
<br>

<div><br>
</div>
<div>We already have compiled opensips as described, and set
memlog=1 in the configuration file. </div>
<div>But as we had a lot of debug messages about memory usage,
we unset memlog=1 in the config, so we don't have any report
now.</div>
<div>Is there a way to get those messages in a different log
file, instead of inside the "classical" opensips.log ? I've
found an option like "memdump" that can be set in
opensips.cfg, but what about it ? </div>
<div><br>
</div>
<div>And as cacti doesn't seems to be relevant to check
opensips's mem usage, do you have any other solution to check
it ?</div>

<div>Thanks for your help, </div>

For debugging potential mem leaks, please look into:<br>

target="_blank">http://www.opensips.org/Documentation/TroubleShooting-OutOfMem</a><br>
If you need help with that, let me know.<br>
<br>
Also, cacti is monitoring the system memory which is
irrelevant for OpenSIPS (as OpenSIPS is
pre-allocating - from OS - all the needed memory at
startup).<br>
