This looks like a media problem to me.

Whatever application did the request (obviously, NBU), requested a 
"space" command.  The tape/drive responded with sorry, EOM is detected. 
  Thats kind of odd since the "Requested Block" is 1.  Typically you'd 
get lots and lots of blocks on a tape.  What happened in the bptm log 
at the same time?
