Hello,

I'm experiencing estimates that are way off with the result that level
0s and 1s use the same space on tapes and now obviously that
throws the balance completely and every amdump eats through a lot
of tapes.
I'm using calcsize in my DLEs but it's the first time that the
estimate are completely off the tracks. It affects DLEs using gnutar
and xfsdump so I'm quite baffled by this one. 

Running Amanda-2.4.5 on clients and server.

For instance look at the sendsize debug file on a client for the DLE
/data/noel/noel1 which is ~90GB big. 

sendsize[1138742]: time 10.002: calculating for amname '/data/noel/noel1', 
dirname '/data/noel/noel1', spindle 2

sendsize[1138742]: time 36.713: done with amname '/data/noel/noel1', dirname 
'/data/noel/noel1', spindle 2
sendsize[1927015]: time 36.714: child 1138742 terminated normally

Strange. Any ideas?
Thanks
