Zimbra startup hangs after install CentOS 4.2

[eger]

I had this same problem on Milestone 3. Just upgraded to the opensource binary install for RHEL 4 on CentOS 4. Upgrade was super smooth, actually very informative yet simple and easy.

After upgrading I still have 1 problem I had when using Milestone 3 plus a new problem.

When starting Zimbra it hangs for a very long time (sometimes hours) at this stage in the log file:

Feb 10 18:35:31 centos zimbramon[4553]: 4553:info: Starting mta

After waiting it out i finally get this in the log file after it (notice the first line has a future date?):

I'm not sure what it's hanging up on yet...

The next problem is that everything is only listening on a ipv6 socket and no ipv4. Here is what the netstat listening sockets look like:

This may be a server specific problem. I may try installing a fresh copy of CentOS 4 and starting a fresh Zimbra install.

Anyone have any ideas?

Are you running in a Virtual machine? Can you identify which process is taking a long time to start? How much CPU/RAM do you have?

[eger]

I am running in a virtual machine with 384meg RAM (for the VM) and 2x2.8g xeon. I was thinking it might have something to do with the VM. I haven't identified which process it is that is taking a long time to load. I will add some stuff to the startup script so I can easily identify the part at which it is hanging.

EDIT:

If it helps at all this is what it hangs at:

root      2162  0.0  0.2  4840  668 ?        S    20:52   0:00 initlog -q -c /etc/rc3.d/S99zimbra start
root      2163  0.0  0.4  5636 1140 ?        S    20:52   0:00 /bin/bash /etc/rc3.d/S99zimbra start
root      2164  0.0  0.4  6164 1220 ?        S    20:52   0:00 su - zimbra -c zmcontrol startup

Wouldn't think that helps tho since it could be anything in zmcontrol. Is there a way I could get it to print out in the console from zmcontrol?

Kinda slim on the RAM... Take a look at this post... Lots of VM's hit this.

Post install : Zimbra start up is taking upwards of 10 minutes

[eger]

Yea I had a similar problem my first try. Eventually everything worked after it finally finished starting.

I just did a reinstall of CentOS 4.2 and Zimbra on a new VM with 512RAM and now everything is starting up within 20 seconds. Guess the VM doesn't play well with java and needs a good amount of memory to play nice.

Now it looks like everything is working great. I can start playing with this wonderfeul open source app! Goodbye qmailrocks!!! =p
