wait for dumping

Hi amanda-users,

I have just encountered a problem with amanda-2.4.4p1...

I run: amadmin Daily force-bump basement furnace media

I then run: amdump Daily

Running amstatus Daily prints that it is estimating.  It then changes to
"wait for dumping" as each estimate is complete.  When all estimates are
complete, amdump exits (without dumping anything) and amstat shows:

basement.krautclan.com:/      1    12963k wait for dumping 
basement.krautclan.com:/boot  1       45k wait for dumping 
furnace.krautclan.com:/       1    17153k wait for dumping 
furnace.krautclan.com:/backup 1     4903k wait for dumping 
media.krautclan.com:/         1   222336k wait for dumping 
media.krautclan.com:/backup   1    13370k wait for dumping 
media.krautclan.com:/boot     1       21k wait for dumping 

and amdump send me email saying:

FAILURE AND STRANGE DUMP SUMMARY:
  furnace.kr / RESULTS MISSING
  furnace.kr /backup RESULTS MISSING
  basement.k / RESULTS MISSING
  basement.k /boot RESULTS MISSING
  media.krau / RESULTS MISSING
  media.krau /boot RESULTS MISSING
  media.krau /backup RESULTS MISSING

There are no errors in the /tmp/amanda/* files.  Full dumps work with no
problems.

Does anyone have any guesses as to what is happening?

Thanks,
Dick

P.S. I am using a tapeless setup which works fine with full dumps, and I
am trying to force incrementals for the Daily runs.
