Ryan added a comment - 21/Feb/2010 10:05 PM IndexingTask.runInternal() method is responsible for this: public void runInternal() { batchIndexer.indexEntities(progress); finishedReindexing = true ; } If batchIndexer.indexEntries(...) throws an exception then the finishedReindexing flag will never be set to true, causing checks by the DefaultConfluenceIndexManager to always think that indexing is still happening.

Igor Minar added a comment - 03/Feb/2010 10:41 PM Just for the record, here is a concrete exception that results in this issue. The root cause of this exception is most likely a very different issue, but the side effect is that the indexing stops.
