Otherwise, I have no problem. It is indeed a panic, but with only 15 seconds, it doesn't give me enough time to write it down. How would I got about debugging this problem?? Any help would be appreciated.

Or did I break something?? I can't say that I have an answer to your question, but maybe a couple things that can help you figure it out. 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.
