Don't know without more information.

Take a look at the amdump.<NN> file for the "got result for host" lines
to make sure what planner was working with.

Then look for the "DELAYING DUMPS IF NEEDED" line, e.g.:

  DELAYING DUMPS IF NEEDED, total_size 33616007, tape length 55296000 mark 2000

This says the total estimated size was 33616007 KBytes, the tape length
(including the runtapes multiplier) is 55296000 KBytes and a tape mark
(space between each image) is 2000 KBytes.

What is your runtapes set to?

>If it hits EOT, then didnt sendsize & friends miscalculat?

Not necessarily.  If someone touch's a 30 GByte file that the estimate
skipped over because it looked idle at that time, the dump will have to
do it and that would throw everything out of whack.

>And is there any consideration on fitting a large partition onto one or
>more tapes?

Definitely.  All it takes is a few weeks of dedicated programming time
by someone and a whole lot of testing.
