[thelist] denial of service? or a badly written script?

Hi,

In a matter of nineteen minutes tonight I got 1145 requests like this to a
site I host:

[Fri Apr  5 23:36:41 2002] [error] (63)File name too long: access to
/tools/tools/tools/tools/tools/tools/tools/tools/tools/tools/tools/tools/tools/tools/tools/tools/tools/tools/tools/tools/tools/tools/tools/tools/tools/tools/tools/tools/tools/tools/tools/tools/tools/tools/tools/tools/tools/tools/tools/tools/tools/tools/tools/tools/tools/tools/tools/tools/tools/tools/tools/tools/tools/tools/tools/tools/tools/tools/tools/tools/tools/tools/tools/tools/tools/tools/tools/tools/tools/tools/tools/tools/tools/tools/tools/tools/tools/tools/tools/tools/tools/tools/tools/tools/tools/tools/tools/tools/tools/tools/tools/tools/tools/tools/tools/tools/tools/tools/tools/tools/tools/tools/tools/tools/tools/tools/tools/tools/tools/tools/tools/tools/tools/tools/tools/tools/tools/tools/tools/tools/tools/tools/tools/tools/tools/tools/tools/tools/tools/tools/tools/tools/tools/tools/tools/tools/tools/tools/tools/tools/tools/tools/tools/tools/tools/tools/tools/tools/tools/tools/tools/tools/tools/tools/tools/tools/tools/tools/tools/tools/tools/main.css
failed for 24.42.99.36

They're all from that IP - it stopped when I shut that address out using
.htaccess. The number of "/tools"s varies among requests (from 2 to a whole
lot)..

The file /tools/main.css does exist, though
/tools/tools/tools/--etc--/main.css obviously does not.

Anyone seen anything like this before?

Cheers,
Noah
