Sounds like a panic to me, is there anything in /var/log/messages? Does it happen if you don't use the mount_null? Throw a couple dummy files in /var/ftp/pub and see if it still happens. Is this a production machine? If not you could enable crash dumps and possibly a debug kernel so you can get more information on the crash. Hope this helps, -Chris P.S.
