Whenever taper successfully writes a dump from the holding disk to
"tape" it removes the original from the holding disk.


You show error messages with little or no context.  Were other
things succeeding?  Are these the only messages that show errors?
Were the dumps making it to holding disk but failing to tape?
Is the holding disk full so it was trying to write to the slow
ftp shares directly?  Is the disk with the ftp shares full?
Is the access sooo ssslllooowww that the network times out and
the error looks to amanda as no more space?
