From Bugzilla Helper:
User-Agent: Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.7.2) Gecko/20040803

Description of problem:
if a pid on gfs was holding posix range locks and the process died from a signal, the posix range lock was not released.  Later, other processes that might try to get the same lock would fail or block forever.  A cluster reset was required to get out of this.

Version-Release number of selected component (if applicable):
cvs head and rhel4 branch

How reproducible:

Steps to Reproduce:
plock, kill, damn.

Easy enough fix.  actually just had the state inverted.  Wasn't calling the
upside posix lock update function when I should have been.  Do that right, and
this bug is gone.

I believe this was fixed about 5 years ago, but was never added to any erratum.
