[Networker] Tape in full mode at less then 40 GB ??

Hi,

I have a Legato Networker server on Solaris 8, with a DLT Librabry (SUN
StorEDGE L20), and everything is working well, with a small(or note so
small) exception.

Sometimes, the tape is declared as full even if no data is written on, or
just with some GB on. IIf I modify the tape mode in appendable, more
backups can be done on that tape.

Any help will be apreciated ;)

Here are the logs:
