Too many files in /var/tmp

[Chris Crowley]

Hey all -

I just noticed that there are nearly 80,000 files in /var/tmp (my
upload_tmp_dir) with filenames like:

-rw-------   1 nobody   nobody         0 Jan  3 14:55 php..ai9I
-rw-------   1 nobody   nobody         0 Dec  5 15:27 php..aiAo
-rw-------   1 nobody   nobody         0 Jan 15 18:25 php..aiCb
-rw-------   1 nobody   nobody         0 Jan  4 15:45 php..aqXc
-rw-------   1 nobody   nobody         0 Dec 10 15:26 php..aycV
-rw-------   1 nobody   nobody         0 Nov 28 15:48 php.0a46R
-rw-------   1 nobody   nobody         0 Dec 13 05:45 php.0a4CS
-rw-------   1 nobody   nobody         0 Jan 23 15:48 php.0a4Lx
-rw-------   1 nobody   nobody         0 Dec 10 06:11 php.0a4MJ


What's missing in my config? There must be some cleanup routing that imp is
not executing properly.

TIA,
Chris
