  $56 is a bad buffer address.  At a guess, this would be an attempt to set a
buffer at an address that isn't on a page boundary, or at an address that is
already in use by the system.  You'd expect to see this generated by a SETBUF
call, which is done to reassign a file to a different buffer.

  Just guessing, I'd vote for 1) page boundary error, 2) due to a corrupt
download of your Zlink software   (If I understood what you're doing,
correctly, that is.)
