Some time ago, Glenn Everhart reported a bug in VMS V4.5 which corrupts cluster
mounted disks.  The corruption occurs when the index file is extended by two
processors at the same time.  The corruption is comprehensive.

I called Colorado to see if they had heard of the problem.  They had not, so
I told them to contact DEC Australia and find out.  I just got called back.
There is such a problem, it appears in V4.5, and an engineer is working on
a patch right now.

Cluster users, beware of index file extensions under V4.5.  As Glenn suggested,
restructure your disks _frequently_ with VMS BACKUP.
