Sorry, I meant to say "I'm using an ORM tool (and so NOT using the DNN Business Controller)."
I did some more investigation and it turns out that the errors occur in pairs - 4 pairs (8 total) about every 1/2 hr. So, I looked at the schedule and only thing scheduled to run every 1/2 hour is: DotNetNuke.Services.Search.SearchEngineScheduler, DOTNETNUKE. So, I folowed the advice in: http://www.dotnetnuke.com/Community/ForumsDotNetNuke/tabid/795/forumid/92/threadid/9003/threadpage/0/scope/posts/Default.aspx, but unfortunately, I'm still getting the errors.
When I manually re-indexed, the errors in the log had a bit more information (I replaced the PortalName, Servername and URL with x's). Any help/suggestions would be appreciated:
