Good idea. I will give it a shot, although I'm pretty sure I'm not the cause.
I have four years experience as a (Open)Solaris system administrator and before that I used FreeBSD heavely. From the 4.10 series up to the 6.x series. So I do know something about the matter. But, we'll see... Keep you posted.
