So I installed WDS 3.01 again and now no reindex mania. Practically same conditions except a minor update to Kaspersky AV. I would think difference is Ive yet to add that many folders. Last time I included almost everything from start, this time I add one at a time. Did exclude some irelevant folders like Temp etc. but most were target. Will assume that was problem.

So the only thing that should need to be recrawled on start-up would be network shares, Outlook versions
prior to 2007, and the IE history cache. If you use Outlook 2007 and haven't installed the IE history or UNC/FAT add-ins, then nothing should ever need to be recrawled in WDS 3.0. That's because WDS 3.0 can read filesystem changes from the USN change journal to make sure it's in sync, and Outlook 2007 knows what has and hasn't been indexed since it "pushes" data into the index instead of having it be crawled like previous version of Outlook.
In those other cases, the indexer doesn't know what's changed since the last time it was running - so it needs to do what we call an "incremental" crawl. It does
not mean that everything gets re-indexed. What it means is that the indexer will walk the folder hierarchy of those datastores, and determine which folders have changes in them. When it finds a folder that has changed, it will go into it and look for the items that have changed (added/modified/deleted), and only process items that have changed.
If you were seeing a complete reindex, or items indexed resetting to 0, or were seeing something like what I described above without having any of those add-ins involved (or with Outlook 2007), then that is not expected behavior and could be a bug, incompatibility, or some form of corruption.
