SEPM 12.1.4104.4130 and Java

Hello,

We have running SEPM 12.1.4104.4130 under Windows 2008 R2 server. In the last couple of days we started receving the following notifications:

Server health status: poor.
Reason: Memory on your Symantec Endpoint Protection Manager server is running low.
Status reported on Dec 28, 2014 8:15:03 PM.

I was checking the server and I have noticed that Semsvc.exe and dbsrv12.exe are the bigger consumers in memory. When I have the console opened, the memory use go up to 65% (Server has 2GB). Is that normal?

Also, we have Java version 7 Update 51 in the server, can we upgrade that version to the latest one? or SEPM 12.1.4104.4130 only works with that version of Java?

Thank you in advance for your help.

Francisco
