If I understand the working of Amanda correctly, Amanda will postpone some full dumps if the estimate of all the filesystems are larger than one tape even though the setup is to use two tape drives. Amanda will write to one tape until the full and write to the second tape. Correct me if I'm wrong. Can Amanda breaks up the backup job so it can spread the filesystems that are backup to multiple tapes? For example, amanda will backup those filesystems that fits on one tape and backup the rest of the filesystems to the other tape which will reduce the postpone of some full backups.

More likely the estimated size of the dump of that disklist entry (DLE) was larger than would fit on the tape. Remember that amanda can not backup a DLE that is larger than a single tape. -- Jon H.
