Steps to Reproduce (i)I have not been able to reproduce this locally with Background Reindexing, but I HAVE been able to reproduce locally using the Index Recovery functionality. These steps refer to that process # Set up Index Recovery # Allow for the Index Recovery process to run at the appointed time (for testing, you can set the time for 5 or 10 minutes in the future) # Once an index recovery backup zip is created, enter in the appropriate zip file name into the UI and click *Recover*. # Near the end of the recovery process, note the 500 error page. h4. Workaround Since the actual indexing process seems to work fine, a workaround may not be needed. However, users can run a full, locking index in lieu of either process to rebuild their indexes from the database if their situations warrant it.
