It looks like this bug has been fixed upstream at the beginning of this
year :
http://webui.sourcelabs.com/rhel/issues/426291

This is an important bug, as it may result in a Denial of Service, due
to services hanging in uninterruptible sleep.

Hi,
I've uploaded a new upstream version which contains a newer GFS
