OS not allowing me to get native fs lock

["Newman, Billy" <Bi...@itt.com>]

I know that this is not really a lucene problem but looking around I have not been able to find much about it.

I recently ran into a problem where I cannot obtain a lock due to a problem with native file system locks.  The strange thing is that this was working a few days ago and I have just started seeing problems today.  As far as I know nothing has changed, but I am sure something did actually change to cause this problem I am just not sure where to start looking.

I get a LockObtainedFailedException... java.io.IOException: protocol family not supported...
Caused by..sun.nio.ch.FileChannelImpl.lock0(NativeMethod)

Any ideas on were to start looking would be extremely helpful. I am running on Redhat 4.
