Tape backup through ssh - Other issues

I have some other issues with dumps over ssh. Maybe someone can give some ideas.

I am doing dumps of multiple remote directories on multiple machines to a local DLT multi-tape robot, using this command:

ssh user@host /sbin/dump 0abuf 63 - /directory | dd of=/dev/nrst0 obs=63

When the end of the tape is reached, dd dies as expected:

dd: /dev/nrst0: Input/output error
3187663+22 records in
25298+0 records out
1632024576 bytes transferred in 1772.209 secs (920898 bytes/sec)

Unfortunately, the dump command in the remote machine does not receive this error and does not die, hanging the ssh connection forever, and making impossible to change tapes as needed.

Any ideas on how to solve this situation? Workarounds?
