Recently I have noticed I am getting the following email alerts from my printing server and then having to restart the server.

“Virtual Memory Performance on server PRINT is in a SUSPECT State, Please Check the server.”
“Virtual Memory Performance on server PRINT has returned to the GOOD State.”
It’s running on the platform;

Netware SP8 support pack 8b running on VMware.
Can someone advise how I can trouble shoot the above....
