So after numerous installs, I ran into an issue with this install that totally hosed a number of servers. The boxes affected were all 32 bit MOSS 2007 enteprise machines, single Server dev implementations using SQL Server 2008 om Windows Server 2008.

 

      On step 8 it would consistently fail. The upgrade logs indicated a conflict in one of the search databases:

"ReflexiveUpgrade [SPServer Name=<machinename> Parent=SPFarm Name=<configDBName>] failed.
[SPManager] [ERROR] [6/17/2009 12:55:20 AM]: An update conflict has occurred, and you must re-try this action. The object SPSearchDatabase Name=<WSSSearchDB Name> Parent=SPDatabaseServiceInstance is being updated by domain\installaccountname, in the OWSTIMER process, on machine <machinename>.  View the tracing log for more information about the conflict.
[SPManager] [ERROR] [6/17/2009 12:55:20 AM]:    at Microsoft.SharePoint.Administration.SPConfigurationDatabase.StoreObject(SPPersistedObject obj, Boolean storeClassIfNecessary, Boolean ensure)"

 

    I tried the solutions posted here:

 

 and other places with no luck. Could not get the config wizard to finish. Out of frustration, I ran the wizard 1 more time, as soon as it hit step 8 I clicked the "cancel" button and allow the config wizard to stop in a more controlled manner. I reran the config wizard right after that and it ran to completion!

 

  Cannot say at this point in time I have any idea wh this worked, what was broken, but in addition to the solutions provided at the link above (which do work for many folks), this is another option to try.
