Could someone also explain what exacty 'broadcast/multicast datagrams dropped due to no socket' means. Any advice that could be provided would be invaluable.

FreeBSD 5.0 Is the top of the line and there for _can_ be very bugy!

You wise to either upgrade to 5.1 or downgrade to 4.x. This could sove 
your problem. The 5.x brance isn't deemed stable and not suggested for 
production enverements. If you upgrade upgrade with care - early 
version (< x.3) have bin know to render code server useless. (You don't
whant this with essential code.)

P.S. Please cut you lines so that they there length is less or equals 
than 72 char.
