Well, that doesn't really tell us more more about what is going wrong,
other than the slight hint the problem is all the way down in the the
libc library somehow.

I don't know how much you are trying to investigate further at this
point in your furlough schedule... but I still feel that comparing the
log from a succesfull run to this aborted run has the best chance of
generating a hint as to exactly what operation is underway at the point
of failure.


Also, the taper/changer logs from last night's run should give some hint
as to what it was attempting, and perhaps those logs will be different
enough from the amcheck-device logs that it'll give some new
information....

(The last operation that appears to be happening in your quoted
amcheck-device log lines is a scan through the tape-changer inventory. 
I don't have a physical tape-drive changer myself so I don't have any
guesses as to what could be wrong, but based on the history of the
situation you described it does seem plausible that the inventory
database it's working from could contain some "unexpected" data of some
sort...)
