[Dirvish] filesystem full - but thats wrong

[Frank Lüken]

Hi i get everyday this message after my backupserver starts the daily backup:
dirvish ubuntu:default fatal error: write error, filesystem probably full
dirvish ubuntu:default fatal error: filesystem full
dirvish ubuntu:default fatal error (12) -- filesystem full

If i restart the Backupserver one day the backup work, but on the second
day it crashes again! The filesystem hat enough free space i think. It is
an ubuntu 8.04 server.

Some ideas?

Greetings,
Frank
