Ok, I'm trying to set this up again on a faster server.
this time it's a 3Ghz+ Cpu /w 2GB Ram & 300 GB HD (Raid5)
Running CentOS 4.2 as the base OS and then a virtual server with CentOS 4.2 as well.
I've setup the disk quota with 150GB allocated to the Zimbra virtal server and 1GB of RAM.
Installed a clean copy of Zimbra Beta3 M4 and it looks like there wasn't any errors.
The problem I'm having is "Mailbox" is not starting, even though it says it is after a zmcontrol start. Seems to be just like this other posting,
Mailbox and logger not starting - SLES9 M3 Beta436
