Memory usage on Zimbra 5.0.2 NE on RHEL 5.1?
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.
15821 zimbra 18 0 2010m 809m 10m S 1 20.5 3:37.67 java
2625 root 18 0 10180 644 552 S 0 0.0 0:00.86 hald-addon-stor
15457 zimbra 15 0 1211m 163m 4300 S 0 4.1 0:17.77 mysqld
1 root 15 0 10316 688 576 S 0 0.0 0:00.43 init
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.
Memory useage on 5.0.2 GA
I use 5.0.2 GA on ubuntu 7.10 server, with memory useage seldom above 500 Megs. (only time was actually during install)
Admittedly I am running it for demo purposes and the load isn't especially high, but it is delivering mails and working with Thunderbird with Lightning and zimbra desktop.
I have reduced ram on this box to 768 Megs.
/etc/security/limits.conf on debian systems may help
/etc/sysconfig/limit* (or something like it on RPM distros)
