etimeout 300

It looks like the estimate phase completes though:

/-- delphi.ahp /u04 lev 0 FAILED [data timeout]
sendbackup: start [delphi.ahpcrc.org:/u04 level 0]
sendbackup: info BACKUP=/sbin/dump

Unfortunately I don't have historical reports to check that.  The
current stats are:

I'm doing a test dump now with just the 2 machines that are having problems.
