But when I add large number of documents into my libraries (about 2000), I see that many documents are still not processed
one month later.
Jean-Baptiste,
Microsoft has confirmed that a single view within a document library should contain no more the 1500 records (Lawrence Liu speaking to NYC SharePoint User Group, Aug 2007). He said they are investigating the cause, acknowledging that it is a major concern.
I'm surprised that you are still able to function at all having that many documents visible in a single library. Try doing it a couple hundred documents at a time, moving the processed documents into an archive center and then processing the next batch. I think you might find you'll start getting better results.
