From the little you have told us, this sounds like a network problem rather than anything to do with the RHEL server.

Sounds like you may have a bad NFS mount. See if you can log into the console directly and unmount any NFS mount points. It may be dangerous to do so in a hung state, but

Code:
umount -l <directory>

should unmount it. Then you can investigate what happened.

Sounds like fcntl locks are being released locally but not on NFS server. Is your RHEL server up-to-date with patches?
