Hello all,

I'm having a problem with my install. I am trying to migrate from Communigate to the Zimbra paltform but keep experiencing a lot of CPU spiking and out of memory errors. I have captured the last event below.

About my system:
-ESXi 3.5 update2(patched) (2) 3.08GHZ CPUs with 4GB memory
-Runs around 15-20% on CPU utilization

The VM:
-1 VCPU with 512MB of memory
-2 mailboxes beyond the defaults
-Remote ISP SMTP server for outgoing mail

I got all the install issues worked out and the system was working last night. I does seem to be slow at times, but I'm working remotely so I can't be sure were the slownesss is.

At any rate the system crashed again this morning with a "out of memory" condition for all kinds of services. Looking at the logs I found that it started with a java invoked condition. Since there was a memory error, I checked my VM stats, but never saw the memory get anywhere close to be fully utilized. It never touched "ballon" memory on the VM either.

I see where it claims to be out of swap memory. What swap memory is this refering to? This obviously looks like a memory leak of some sort. Any ideas what to doo next?
