A workaround to the DU 4.0 and DU 4.0a dump problem with stdout is to use a
3.2C or 3.2G version of dump. Thanks to

Known and reported problem in V4.0 and later "dump". What I *think* it's doing is that
if you are trying to dump to something other than a tape, it tries to figure out if
there is enough space for the dump, but if the output is stdout ("-"), then instead
of bypassing the test, it looks at the available space on the filesystem that it will
be dumping, and if THAT wouldn't hold the whole dump, you get the error.
The "workaround" is to get the "dump" from a V3.2C (or V3.2G) system and use that. It
will run just fine on V4.0 and doesn't have the problem you describe. It may well
have some other problems that got fixed in the V4.0 dump, but I don't know off the
top of my head what they would be.
I don't think the problem you describe has been fixed in V4.0B, which picks up most
of the known patches.
