Strange logfile entries: 8\r\xff

Hello,

some of our users noticed, that lines like this appear in their logfiles:

58.187.78.42 - - [14/Mar/2010:04:38:53 +0100] "8\r\xff" 400 226 "-" "-"

This has been noticed be different customers on different servers. I
know that the Referer and Useragent may be empty (shown by the dash),
but URI part should at least start with GET or POST.

I found nothing with Google on "8\r\xff" but it seems that something is
talking to our servers with invalid HTTP. Is "8\r\xff" used to exploit a
webserver, but it simply didn't work out on our servers? Has anyone else
noticed such entries in the logfiles?

Kind regards
Marten
