    Typically, a couple of tapes into a backup, the backup will stall, with
    each machine waiting on the other (I've included complete backtraces
    for both machines at the end of this message.)

Your backtraces don't show them each waiting on the other.  The file
server is waiting for the tape server (it's in a "Chaos In" wait, i.e.
it is waiting for data from the Chaosnet), but the tape server is
waiting for something from the cartridge tape drive (it's in a "Cart
Tape" wait).  It may be a problem with the tape or with the tape drive.
