Hi, The existence of the write.lock file has nothing to do with actual locking. The lock file is just a placeholder file (0 bytes) on which the lock during indexing is applied (the actual locking is done on this file using a fnctl). When indexing finishes, the lock is removed from this file, but the file stays alive. This was different in Lucene 3, where the lock was also removed. But this caused problems because of non-atomic file operations. Lock factory only checks the "lock on the file", not "the existence of the file as a lock".
