This is a message from your mtx command and tape library.
I see nowhere in the chg-zd-mtx code where this is an anticipated message.
It is expecting something like "Slot empty", or "Storage Element 9 Loaded".

chg-zd-mtx depends on the changer and mtx telling it what is loaded.
If your changer doesn't know what tape is loaded, chg-zd-mtx can't either.
Maybe it needs power cycling or reloading or some such?

Why disable autoclean and yet leave an unavailable slot for tapes?
How about lastslot = 10 and cleanslot = -1 ?
