Hi,

I am running a Zimbra NE on RHEL. The machine has currently 65megs free memory which is a bit alarming. I am setting up a new environment which is being migrated from the FOSS server.

The machine is a Core2Duo 3GHz with 4GB of RAM running on 64bit RHEL5.1. It seems that Java and mysqld take up more than 90% of the memory and this machine is NOT even receiving any mail.

How can I lower the memory usage, since I am a bit worried that I will need more memory when it hits production.
