This helps you to clear your memory ram avoiding your server to overload.
Add this line to:
/usr/local/cwpsrv/htdocs/resources/admin/include/3rdparty.php
<li><a href="index.php?module=clear_memory_ram"><span class="icon16 icomoon-icon-arrow-right-3"></span>Clear memory ram</a></li>
Then create a new file called "clear_memory_ram.php" on:
/usr/local/cwpsrv/htdocs/resources/admin/modules
with this content:
<?php
exec('sync; echo 3 > /proc/sys/vm/drop_caches');
echo "Done!!";
?>
