The AVIV cards are quite old I would wager.  Given that assumption,
DEC had a problem with a batch of defective propriotary q-bus interface
chip sets.  As I recall they had the same problem, and it probably gets
worse with age.  Dec didn't seem to have any of their own cards affected
but sent notices to all licensed developers of cards.
You may find help from the code info on the bus interface chips and your
local dec office.  The digital unlisted spares program MAY also have info
of this type.  I'd say your chances of getting the replaced for free are just 
about zero, and the chip set costs about $100, if you can buy it from that
same spares program.
