High memory Checkpoint 5000

We are experiencing high memory on the checkpoint gateway. Is there any way to help me determine where the problem is coming from?

you can ignore what OS tells you about memory use. What's important is this:  

 

Memory used: 31% (3714 MB out of 11794 MB) - below watermark.

It says, you are fine

For information 5000 series gateways can have up to 32GB RAM installed.

My preference is to avoid situations where the gateway must rely on swap.

You can run ps -auxw and see what process consumes most memory. Also, execute cpview, thats super helpful for anything you need to check on the appliance.
