The lsof (list open files) package should be able to point you in the
proper direction. A word of warning, tho... it's VERY specific to
whichever kernel it was compiled for. If you're not running one of
Debian's "stock" kernels, you'll probably need to compile it yourself
(if you need a quick rundown of the "debianized recompile" procedure,
let me know... it's REALLY easy, tho).
