[bug food]

     Well, I took that giant leap of faith forward and installed VMS 4.6...
So I'm wondering if anybody else has had the following problem, or if it's just
a hardware problem:

     Hardware in question: 11/750 (we're on a tight budget...) and TU81+. (The
750 is the boot node of a LAVC that includes a uVAX II and a Vaxstation 2000.)

     Software in question: Backup or DCL.

     Problem:  I have a command procedure that does the backups that I need to
do when I need to do them.  It backs up various disks to tapes mounted on the
TU81+.  When run as a batch job (usual case that worked fine under VMS 4.5C)
the following BACKUP command generates the errors:

$       backup/image/ignore=interlock/jour=BACKUP$JOURNAL:MONTH10_MATH2.BJL -
                MATH2: -
                MUA0:MATH2.bkp/block=32528/density=6250/label=D31006 -
                        /norewind/buffer=5/nocrc/fast
%BACKUP-F-LABELERR, error in tape label processing on _HELA$MUA0:[]MATH2.BKP;
-SYSTEM-F-BADPARAM, bad parameter value

When the *exact* same command procedure is run on the console terminal (a
DECwriter III) with verify enabled it works just fine, and does *not* generate
any such errors.

     Both processes are running at prio 4 and have the same privileges.  I have
attempted to place a wait statement prior to the backup command thinking that
the tape drive needed a minute or two to synchronize, but that didn't help.
Anybody have similar experiences?  ideas?  (Shooting that tape drive at dawn
isn't an option  :-)  )  I am currently suspecting 4.6 backup, but I cannot be
certain.
