There is one general problem with GNUtar and incrementals:
The unix ctime must not change. Otherwise you get just this result
incrementals being full backups.

The typical reason for changing ctimes is GNUtar running
with --atime-preserve option. You might check your runtar debug
files for this option and verify 
with 

ls -al --time=ctime <some important file or directory which has'nt changed>

that you ctime are correct.
Please also check (and perhaps mail here) the output of 

amadmin <your config> version

Some older versions of Amanda had a configure option
--with-gnutar-atime-preserver (unsure about spelling) which is
incompatible with GNUtar and incrementals.
