Search ReIndex never successfully completes

I am at a loss to what is causing the error below. I have reduced the Search options to only do Static HTML Pages, Have encapsulated CustomWidget ItemDatabound logic with 
if (this.Page.Items["IsInIndexMode"] == null)

I've even tried to debug and step thru search logic to identify the offending object

Is there anyway to identify the offending object?

I've now Unpublished all Published Pages, Created a page using the standard three row template from the included templates. So there should only be one page to index and that page should not cause an error.

Log file still shows same error above.

Hello John,

My advise is to delete the old search index and then try to create a brand new one. When you delete it from the backend of your project please check ~/app_data/sitefitiy/search folder for any leftover files. The next step is to create a brand new index and try to re-index the only published page. Using this approach you can determine whether there was a problem with the previous search index itself. I would recommend to try this on a backup of your project first.

Folder(s) do not get deleted or generated, This is something new, I watched the directories getting deleted and regenerated last week.
App Pool Entity has full control over app_data directories, Network Service has Modify rights, iis usrs has read execute.

I'm Stepping back, This is a Dev Instance of the project, I am in the process of creating a clone of the production server and will start over with this. 

In the current state, the only way to get the Search Reindex to complete is to turn off Static HTML in page. But this misses 98% of the site. Most information is unique on each page is in unshared content blocks.

If I create an index, indexing doesn't appear to start until I click on reIndex, then I get the message above. If I then try to ReIndex again, watching the parent directory, the directory sometimes goes away, sometimes not. So I then create another index, tell it to index, and the new directory appears, usually has about four files in it, then the message appears.

Thank you for the assistance.

Ok, Have a fresh Clone of the production server, Created a new index.

Directory was not created, so I ReIndexed the new index, still no directory created.

I created the directory, ran ReIndex, watched the directory disappear, but not recreate.

This worked previously, I'm not sure where to look at this point, 

Hello John,

It seems that something displayed on a page cannot be indexed and this might be the reason you cannot re-index. I would advise to open a support ticket where you can provide a copy of your project and I can inspect the problem in details on my end.

Thank you Kaloyan, 

To anyone else that is encountering this error, it turned out to be redirect pages that had invalid links, deleted or moved within sitefinity. During testing on a cloned instance of the site and database, I deleted all redirect pages and reindexed, index completed successfully, then on the production site, I went thru all redirect pages and confirmed each link was valid. After this Re-indexing completed successfully.
