Hmm, not good. Can you share more details about how your app is using Lucene?
Do you also have an IndexReader that's open on this directory? Do you reopen it after indexing documents? If so, using IndexReader.reopen or by closing and opening a new IndexReader? Or, by getting a near real-time reader? Are you closing the IndexWriter after each batch, or calling commit?
