Differences between "df -m" and summarized "du -sm *" in FC4

[Joachim Backes]

Hi,

having an FC4 server and problems with /tmp:

df -m says, that /tmp 100% full. But if going to /tmp, calling "du -sm *" and summarizing all sizes 
gives a huge difference against the df command (the sum is about 10% of the df-value).

Remark: there are no .-files in /tmp so "du -sm *" fits all files in /tmp.

Can somebody explain this behaviour?

Regards
