Inconsistent /tmp Sizes

[Kenneth Jacker]

[ Sorry to start a new thread, but somehow I deleted the previous letters.  -khj ]

As you might remember, I wrote some weeks ago about the gradual use of
disk space in my (Kubuntu 7.10; 2.6.20-16-generic) /tmp partition.

Adding to the strangeness if the fact that two different "disk
utilization" programs produce different results:

     # du -sh /tmp
     423K    /tmp
     
     ~# df -h /tmp
     Filesystem            Size  Used Avail Use% Mounted on
     /dev/sda6             464M  421M   19M  96% /tmp


Øyvind Stegard suggested that I use 'lsof' to provide more information ...

Here is the output of "# lsof +D /tmp":

and of "# lsof | grep /tmp | grep deleted":

Name: lsof.tmp.deleted

One other *very* interesting data point:  if I logout of my KDE
session, and then log back in, the used blocks in /tmp are deleted!

(Quickly reviewing those attachments suggests that "/tmp/kde-khj/*" is the culprit!)


Hopefully, the above information will help to find a "fix" for this problem.

Thanks for everyone's time,
