Hi,
        I've failed to find this precise error condition in either the 
amanda or Tru64 archives, so any hints as to solutions would be most welcome.
Sorry for the length of the appended logs, but I hope by including them 
I've provided enough data to enable someone to point me in the right 
direction.

Cheers,

Sean



Context:
--------
Amanda server:  OpenBSD 3.2, (amanda 2.4.2p2)
Amanda client:  Tru64 V5.1A, (amanda 2.4.2p2)
Amanda client operator == amanda (group system), which owns the amanda 
binaries.  Tru64 disk devices are owned by root:system with permissions 660.
Amanda client filesystems are UFS, and are definitely online during this 
operation.

Problem:
--------
'amdump Daily' when run on the amanda server fails when trying to backup 
Tru64 client.  It succeeds, however, when backing-up other clients 
(OpenBSD, Debian).  Logs show failure at the client's estimation stage
(i.e., sendsize).  'amcheck Daily' when run on the amanda server reports 
no error when checking the Tru64 client machine.
