Description Robert Jones 2003-02-12 17:42:17 UTC
Description of problem: When an application dies unexpectedly while holding a 
file lock on an NFS mounted filesystem, the nfs-utils doesn't clean up the NFS 
locks.

Version-Release number of selected component (if applicable): nfs-utils-0.3.3-
5.1

How reproducible: Every time.

Steps to Reproduce:
1. Run an application that writes data to an NFS mounted drive.
2. Terminate the application with a kill -9
3.
    
Actual results: The there are still read and write locks on the file belonging 
to the dead processes' PID.

Expected results: There would be no locks held.

Targeting this for RHEL3 U3, changing component to kernel.  -ernie

A fix for this problem has just been committed to the RHEL3 U3
patch pool (in kernel version 2.4.21-15.1.EL).
