I think I have resolved the problem. I was using Lucene to index several directories concurrently within the same JVM, and as far as I can tell Lucene cannot do coucurrent indexing. Is this correct ?

Hi,
I have been using Lucene to index a large directory, indexing HTML and text files. However during the indexing process the entire system stops, that is the IndexWriter no longer adds Document objects to the underlying index directory. Also, this seems to happen at random occasions, that is, it rarely fails on the same HTML or text document.
Below I have attached the exception, once this has been thrown the index directory is not longer updated. I can still add Document objects to the IndexWriter without any problems, however indexing ceases. If anyone can provide suggestions as to what the problem is I would appreciate it.
