Yes, that one is a timeout on the backuppc side.

Are these 2 different scenarios (the sigalarm and sigpipe)? I don't
think I've ever seen a real deadlock on a unix/linux rsync although I
always got them on windows when trying to run rsync under sshd (and I'd
appreciate knowing the right versions to use if that works now). The
sigpipe scenario sounded like the remote rsync crashed or quit (perhaps
not being able to handle files >2gigs). This looks like something
different. Can you start the remote strace before the hang so you have
a chance of seeing the file and activity in progress when the hang occurs?
