Hi

This is a quick general NFS server question.

Does the NFSv4x  specification require or recommend that:   the NFS server, after some reasonable time, 
should / must close orphan / zombie open files ?

On several NAS platforms I have seen large numbers of orphan / zombie open files "pile up" 
as a result of Kerberos credential expiration.

Does the Red Hat NFS server "deal with" orphan / zombie open files ?

Thanks

What do you mean by "zombie / orphan" here? Do you mean files that have
been sillyrenamed [1] to ".nfsXXXXXXX" ? Or are you simply talking about
clients that are holding files open for a long time?
