Inconsistent /tmp Sizes

[Kenneth Jacker]

[  Kubuntu 7.10;  2.6.20-16-generic #2 SMP ]

I am showing an inconsistent /tmp usage value (hidden partition use?):

      # du -sh /tmp
      663K     /tmp
      
      # df -h /tmp
      Filesystem            Size  Used Avail Use% Mounted on
      /dev/sda6             464M   52M  388M  12% /tmp

The output of "ls -Rs /tmp" is consistent with the first value.

Apparently whatever the later ('df') uses is also used for internal
checks since I first found out about this yesterday during a download
("partition full" error message followed by process termination).

Rebooting (I hated to reset my "uptime"!) caused the values to be more
or less equal.  The above numbers are after about 24 hours of use ...
implying that the "disk full" condition will most likely reoccur.

I looked around some, but could find no information/explanation.

Any ideas?
