<div class="moz-cite-prefix"><tt>Hi Kevin,<br>
<br>
For debugging potential mem leaks, please look into:<br>
<a class="moz-txt-link-freetext" href="http://www.opensips.org/Documentation/TroubleShooting-OutOfMem">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>
<br>
Regards,<br>

<div style="font-family:arial,sans-serif;font-size:13px">My
first idea would be to increase the P_MEMORY value to 8 for
