Solaris 2.3 ndd bug

I discovered a, er, shortcoming of /usr/sbin/ndd under Solaris 2.3 this evening.... I was poking around, trying to learn more about the system I live in/with, that sort of thing, when I tried: /usr/sbin/ndd /dev/udp udp_status Boom! Instant kernel panic. I'm logged in from remote, so I didn't get to see all the nice messages, but this is the line in /var/adm/messages which seems relevant: Feb 6 01:52:21 iron unix: panic: recursive mutex_enter. mutex fc0acb50 caller fc02dabc I, um, reproduced it on another Solaris 2.3 system, so it seems like a real bug. And as I see it, this is a reasonably large one. Not only does it show a less-than-complete run of testing of Sun's udp code (I daren't try it with other devices until I have a test machine), but it could theoretically present an interesting denial of service attack. Anyone care to try it on 2.[24] or anything else w/ ndd?
