Greetings,
here is the summary of responses to my query, No real solution, but lots of
hints
The problem seems to exist at many sites, but nobody really
have a reason for the failure.
It might be related to the SunOS st driver, the EXB-5000,
some other SCSI device in the chain, power supply noise,
etc...,
I suspect tape defect, so I will be ordering better quality tape.
During the last week, I saw no failure on 6 tapes, while the
week before I had 3 failures in a row.
I will investigate further during the week.

Greetings,
I have a EXB-8500 in a EXB-10i stacker hooked to a SparcStation1 under
SunOS 4.1.2, no patches installed.
About every tape I use finished with the following messages:
We use SONY P6-120MP (10/09/91)
I had the 8500 replaced because of a mechanical problem, but the error
still happen.
