Description

If we  set "/oak:index/indexName/entryCount" to a Long multi-valued property. That will cause the system to reindex in a loop... You only see the root cause if debug level logging is enabled. There are likely other such problems. Oak should log a proper meaningful exception for config errors, and if possible not get into this loop. It also blocks other indexes to be updated I think.
