I'm running Zimbra on CentOS inside VMWare. The guest operating system has 768 megs dedicated to it.

For some reason even with a completely idle server the box is way too active:
top - 05:18:52 up 3:55, 2 users, load average: 0.84, 1.02, 1.01
Tasks: 93 total, 2 running, 91 sleeping, 0 stopped, 0 zombie
Cpu(s): 0.0% us, 2.9% sy, 0.0% ni, 95.2% id, 0.0% wa, 0.0% hi, 1.8% si
Mem: 775776k total, 698040k used, 77736k free, 46652k buffers
Swap: 524280k total, 0k used, 524280k free, 370344k cached

Java gets run every 30 seconds or so, perl is run every 30 seconds or so. I would love to run this on our vmware server farm but this load for 0 users is quite excessive. Can anyone shed some light on why these processes are running so often on a completely idle server?
