Inconsistent /tmp Sizes

[Øyvind Stegard]

As suspected, lsof gave the answer:

Lots of deleted temporary files opened by the konsole process. The dir
entries are removed from the fs, so 'du' won't pick up this space as it
recursively traverses the directories under /tmp, summing up the usage.
But the blocks have *not* been freed from the file system, because the
file handles have not been closed. So 'df' reports the actual block
usage.

Here's another guy who apparently has the same problem:

(he got no replies, it seems)

You should probably file a KDE bug report, or investige if you can turn
off unlimited scroll-buffer or buffer saving, or something of the kind
(I don't use konsole, myself). Look into a konsole temp file that hasn't
been deleted, and try to see what's being stored in it. It might give
you a hint as to what you can configure to change the behaviour. My
guess is scroll-buffer-storage.
