Since our IBM tech started replacing the cleaning brushes in our drives
every 6 months the number of tape related problems we experience has
dropped dramatically.

Bruce - You can verify that the 3494 is actually doing cleanings by
        periodically running:  mtlib -l /dev/lmcp0 -qL
where the "avail 3590 cleaner cycles" should decrement over time.
Air pollution and dust don't help matters.  Consider having your CE
do a periodic wet cleaning (a manual task, opening the drive), and
note if the problem disappears after such a cleaning, to see if
cleanliness is the issue - which the TAPE_DRIVE_CLEANING record would
seems to indicate.
