Perhaps in the next version, the AMANDA Powers-that-be could change this
error message to read, "The total size of all of today's dumps exceeds
Tapelength size."
Is more clear than, "Dumps way too big, must skip incremental dumps."
...Unless my version is somehow untrue.

I believe amanda tries to tell you that it must skip the incremental
dump, because there is no room on the tape to put both the full of
/maildb and the incremental of /maildb2. What is your tapecapacity?
I guess it's about 35 Gbyte.
I notice too that a level 2 for /maildb is almost as large as a level 0.
I guess the same is true for /maildb2. That means that the estimated
size for /maildb2 with compression is about 15 Gbyte. 20+15 = 35Gbyte.
This means that both of the filesystems do not fit on one tape anymore.
When a filesystem is overdue, it gets a higher priority. When the
priority gets high enough, you should observe the opposite:
/maildb will fail, and /maildb2 will succeed.
I'm not sure when that priority gets "high enough", though.
Is this what's happening?
