Actually Lucene can work over NFS, except, it's not a well tested combination.
However, because NFS does not protect open files from deletion, you
must use an app-specific d

Thanks Uwe, that helps explain why the lock file is still there.
The last piece of the puzzle is why someone may see exceptions such as the
following from time to time:
java.nio.channels.OverlappingFileLockException
at
sun.nio.ch.FileChannelImpl$SharedFileLockTable.checkList(FileChannelImpl.j
This is because Lucene uses Native Filesystem Locks. The lock file itself is
just a placeholder which is not cleaned up on Ctrl-C. The lock is not the file
itself, its *on* the file.

I do not actually take the trouble to specify what Lock Factory to use,
hmmm.
Are you suggesting that because I'm using FSDirectory.open() in my code, I
get a locking scheme that works ... while on other machine for other folks,
they get one that runs into issues and throws
java.nio.channels.Overl
Likely you are using NativeFSLockFactory?
In which case, a leftover lock file does not mean the index is in fact
locked, since the OS will [correctly] release the lock on process
exit.
