DNN generates a lot of "General Exception" errors in the log viewer.  Apparently due to search/re-indexing?  It's a maintenance headache since, over time, a large number of entries are generated.  The issue seems to have been around since at least 03.01.00.  I keep hoping it will be resolved with one of the upgrades, but I just upgraded to 4.4.1 on my development system and the problem still exists.  It also exists on 2 other sites which are now at 04.03.06.  One of the sites is very bear-bones (have only added a single custom module and 1 skin), so I'd be surprised if it was the configuration.

I did some investigation and it turns out that the errors occur in pairs - 5 pairs (10 total) about every 1/2 hr.  Looking at the schedule, the only thing scheduled to run every 1/2 hour is: DotNetNuke.Services.Search.SearchEngineScheduler, DOTNETNUKE.  After searching the forums, I found and followed the advice in: http://www.dotnetnuke.com/Community/ForumsDotNetNuke/tabid/795/forumid/92/threadid/9003/threadpage/0/scope/posts/Default.aspx,

Unfortunately, I'm still getting the errors.  Below is a copy of the log file entries which are generated by the manual re-indexing (I replaced the PortalName, Servername and URL with X's).  These entries have a bit more information than the ones generated when the scheduler runs.

I know others have had this issue (seen the posts) and I've placed a couple also.  It would be great to get this resolved - any ideas?

Maybe there is a problem with the Search Engine?

Here's an example of the entries in the log file.  This is on system running DotNetNuke Version 04.03.06.
