High memory usage

Hi,

The Opscenter has detected a high memory usage on 1 of the server.

I noticed that ZFS is quite high and looks unusual. But i recalled that there was an similar issue previously and someone told me it is normal and there is nothing to worry about.

I would like to do some basic troubleshooting steps first.

Please advise.
