Eric,
 
The interpreter failure and the fix that you mention do not apply
CMS release 5.  At least that is what I was told by Level1.
 
The node that complained is LAVALVM1, is at CMS release 6,
(VM/SP 4 according to PEERS NAMES), so it sounds like LAVALVM1 is a good
candidate for the fix.
both MCGILL and OHSTVMA are on CMS r5.
