We were waiting to upgrade due to some issues with 2008 AD with being able to log in.
Have these issues been fixed in the 5.5b release?
I have not been able to find any direct answers and I have review the release notes, but it's better to be overly cautious.
If VMware called it a bug in 5.5.0 i'm sure they fixed it in either 5.5.0a or 5.5.0b. If you could remember the iisue you will find it in either of the release notes under fixed issues.
Hope that helps.
Any particular error you know of?
This is the release notes of 5.5.0b release vCenter Server 5.5.0b Release Notes
Check all the fixed issues and see if you can find the error you are looking for is fixed.
I forget the name of the main one we were concerned about, but when 5.5 was released originally, vmware had the bug posted at the top of the webpage.
