Question around IndexCommited

Hi All

I have a customer on EV 10 sp2 and we are seeing some strange behavior around the Indexing

The users are not seeing consistent Indexes in AE and search. I can see  in the JournalArchive table  the IndexCommited column that there are thousands of items with a value of 0. This tells me that these items have not been added to the Index so it explains the user Index inconsistency. Yet the EV monitoring isn't picking this up. Before the upgrade it would as per the article below

http://www.symantec.com/business/support/index?page=content&id=TECH50268&actp=search&viewlocale=en_US&searchid=1353652979929

My question is why would the EV monitoring not reflect these missing items in the Index. We do have a call open with support but they are looking at underlying Index issues and not this specific anomaly

Thanks
