If I understand your question; you are showing full physical memory utilization AND you are starting to see swap usage (>0). My inclination is to reboot/restart the gateway during a maintenance window. Linux has a tendency to used free memory to cache frequently used files to speed up the performance of the device. Unfortunately, this also decreases the "free" memory. The solution is the reboot; normally once every 6 months with a failover, actually not a bad idea since you are confirming the boot sector.

HTH!

Hi Stelios,

I suggest to start from investigation step and make sure, that there are no configuration problems. Please provide more information about your device, version, setup and blades which you are using.

On what exactly?
Gateway?
Management?
Precise version/JHF level installed?
A dump of running processes might be useful also.
