Subject Re: Error: Repeated service interruptions - failure processing document: Read timed out

Hi Ronny,

One minor thing: you should need to set throttling to 2 ONLY for the
Windows repository connection, not for AD or Solr.

As for how to debug this issue, first off you should be looking in the
manifoldcf.log file (or the equivalent).  You should see WARN messages from
the shared file connector under most conditions when there's a service
interruption.  You would probably see "Read timed out" warnings if you
looked there, since that is what aborted the job run, along with a stack
trace.  However, that's not going to add much information to the analysis
at this point.

What might be valuable is to determine whether the problem is happening on
the Windows side or on the Solr side.  At this point I can't tell.  You
could, however, create a null output connection, and create  a similar job
the sends its output there, and see if it completes.  Can you do this and
get back to me?
