Problem:  We started noticing hardware inventory failing right after we applied the 1706 update.  The management point was getting flooded with error messages like below Message ID: 5416 and the retry outbox filling up with thousands(25,000+ for us) of retry files.  There were no changes to inventory settings or issues with the configuration.mof file as far as we could tell.  We also checked for replication issues and DP corruption issues but nothing came up as a problem.

MP needs to reload the hardware inventory class mapping table when processing Hardware inventory. The MP hardware inventory manager cannot find a WMI class definition in the mapping table when processing a report. This should only happen if new definitions beyond those known to the site are added to the collected classes.

 

Possible cause: Inconsistent way the new definitions have been introduced.

Solution: Check that the mapping tables contain the information consistent with the hardware definition tables and that the definitions have been propagated properly.

Possible cause: Corruption of the data base.

Solution: Check the consistency of the data base.

Solution:  The solution ended up being pretty easy but frustrating, all we had to do was modify the hardware inventory classes(we added a class) in client settings and let the clients recompile inventory.  After doing that the retry box gradually went down as systems sent in inventory with the new settings and inventory is now updating in the database.
