strange error files

[Jason Majors <jason@whizzird.net>]

I get strange empty error files in my root directory.
I have no idea what causes them.
Here's a listing:
-rw-------    1 root            0 Oct 12 21:49 errs3IY3FQ
-rw-------    1 root            0 Oct 15 20:56 errs83W4Qt
-rw-------    1 root            0 Oct 16 22:48 errs8oJuts
-rw-------    1 root            0 Oct 15 18:51 errs8yTgVd
-rw-------    1 root            0 Oct 17 12:21 errsLuZWMg
-rw-------    1 root            0 Oct 13 10:04 errsMaXwZ8
-rw-------    1 root            0 Oct 17 12:58 errsN9XEXL
-rw-------    1 root            0 Oct 12 17:49 errsU99Kg2
-rw-------    1 root            0 Oct 14 08:20 errscI7gTQ
-rw-------    1 root            0 Oct 11 22:23 errso6ELHV
-rw-------    1 root            0 Oct 16 08:41 errsuicVx6

Does anybody have any idea how I can keep them from appearing?
Thanks,
Jason
