Looks like the mtx-changer script takes too long...

The autochanger might be stuck, or rather, mtx doesn't return but
waits indefinitely.
Don't ask me for reasons, though...

Storage daemon configuration, Device Resource, "Maximum Changer Wait"
directive (iirc, this takes seconds, without qualifier, as an
argument, not something like "10min"!).
Also, you might run the mtx-changer script with debug output to a file
and observe what it does, and were it stops doing things.
Hope this helps,
