If this is occurring when you are creating an index that is not currently being searched it could be:
1) Another process is accessing the file. I've seen disk defragmenting tools do that. 2) Do you have more than one instance of an IndexWriter? The IndexWriter class is thread-safe internally to allow multiple threads to add documents to it. From my experience however I would dissuade anyone from doing that on a high load system as the locking performed internally will cause a bottleneck. Or it could be something altogether different... Anyone else have any ideas?

This is occurring on the search side. I just have one physical index. When adding items to index, the same index is being concurrently searched as well. But the problem occurs when I'm trying to do a full index as well at a location where there are no searches being performed. Is there a fix for this?

Are you indexing and searching the same physical index? Is this occurring on the search or index side? I would encounter that error in 1.9 when Lucene would merge segments and attempt to delete the old one. Lucene will attempt to delete a segment after it has merged and if it fails, it will save the segment file name in the 'deletable' file and attempt to perform the delete at a later merge.

An interesting thing I've noticed is that when I run the indexing process from within Visual Studio Environment (Using NUnit), I don't get this error. It's only when I run the indexing operation as a service or a console application that I get these errors. Someone please help!
