Hi

I'm running FreeBSD 7.0-BETA4 (AMD64) on Intel Pentium 4 630
(EM64T/HT) on Intel D945GNTL motheboard. I'd this crash when I was
running in GNOME, playing with Avahi and nss_mdns to get mDNS over
IPv6 working.

The crashdump is 311 MiB, and after bzip2-ing it comes to around 55
MiB, which is still too big for me to upload it somewhere. Any other
thing I can do to help developers troubleshoot this problem, please
let me know ?

Will FreeBSD 7.0-RELEASE be recommended for production systems. I'm
thinking to use it for my this machine (which is this desktop). I'm
thinking to switch to FreeBSD fulltime, is FreeBSD 7.0 recommended ?

TIA
