[SOLVED] zcs-5.0.18_GA to zcs-6.0.2_GA - stats not running and CPU load spikes...

[mlcdigital]

I was running our Zimbra deployment on Debian 4 and zcs-5.0.18_GA as a VMware host with 2CPU and 1GB RAM (it is a crappy old server).
We were lucky enough to get funding for new server hardware (Dual Optron, 16GB RAM, 5TB RAID 50). It's running Debian 5 with VMware Server 2.0.2 smoothly. I slowly moved virtual machines over...
The last one I migrated was Zimbra. Once migrated I increased it's memory to 3.51GB (32bit build) turned it on and verified all was good. I then did Debian 4 updates and upgraded Zimbra to zcs-6.0.2_GA.
Everything seemed to be running smoothly for a couple days and then...
Stats stopped running. I could turn it back on without errors and view stats in the admin interface but in a few hours (cron job?) it would be off again. I'm also noticing CPU loads spike to 100% then drop down to 50-60%.
I've tail -f /var/log/zimbra.log during the spikes/stats-down but saw nothing unusual.

zimbraserver:~# more /var/log/zimbra.log | grep stats
Nov 16 07:52:01 zimbraserver zimbramon[320]: 320:err: Service status change: zimbraserver.domain.tld stats changed from stopped to running
Nov 16 12:20:15 zimbraserver zimbramon[320]: 320:err: Service status change: zimbraserver.domain.tld stats changed from running to stopped

It looks like this might be a VM issue. This is the VMware Server...

If it's not a VMware Server issue would this be the next place to dig even if I'm going from Zimbra 5 to 6...?
Troubleshooting High CPU load average in ZCS 5.0.x as compared to 4.5.x - Zimbra :: Wiki

I think I've pin-pointed the issue...
Debian 4 kernel 2.6.18-6-686 isn't 100% SMP compliant, at least running on a VMware host with compliant virtualization CPUs. The mail archive server is running Debian 4 kernel 2.6.18-6-686 but with one CPU and it runs smooth.
I'm setting up a new Zimbra VM running Debian 5 kernel 2.6.26-2-686 and will attempt to migrate /opt/zimbra over.
Are these the most recent and accurate directions to migrate Zimbra?

Yes, they will get you to a new server.

[mlcdigital]

I tried following the steps located here a couple times with no luck.
Moving ZCS to Another Server » Zimbra :: Blog

I'd like to focus on the errors existing on the live server after the upgrade from ZCS 5.0.18 to ZCS 6.0.2...

1. Stats stops after 3 hours'ish and I can restart stats it with no errors.
2. Secure IMAP/POP isn't working.
3. I go into the Zimbra admin interface to verify IMAP/POP settings. The interface is slow and doesn't look correct.
4. When I hit save on Server -> Server.Address I get an error like...
   

   JavaScript error encountered in method ZaXFormViewController.prototype.fireChangeEvent
   name:TypeError message: 'this_toolbar' is null or not an object number: - 2146823281 description: 'this_toolbar' is null or not an object

5. I tail -f /var/log/zimbra.log during my tests and didn't see any errors.
6. Who knows what other problems also exist...?

I'm afraid if I do successfully migrate our /opt/zimbra over to a fresh server these issues will just follow...?
Is there some kind of repair or reinstall process to potentially rebuild everything and maintain the existing data?

After a week of running on 6.0.2 I've come to realize it's not stable yet so I had to roll back to 5.

I have also run into that error. We just upgraded from 5.0.13 to 6.0.3.

This happens when trying to save a "GAL Configuration" screen. Which, btw, is broken which is why I'm trying to edit it. After this error, opening up the config screen again reveals that the edits aren't saved. :( Can't try to resolve my GALsync issue till I can edit the config!

[emiro]

Also, in IE the "details" look the same as mlcdigital's last post. IE and firefox differ on the description of the problem. Also, I was able to make changes from "external" to "internal" but no details regarding galsync account name/datasource, etc are saved.
