Hi there, To further explain this: This does not happen when I don't use mount_null. There are no messages that give any clue in /var/log/messages or the ftpd log file. Any ideas? :) Thanks, Marc -----Original Message----- From: Christopher Michaels [mailto:ChrisMic@clientlogic.com] Sent: Monday, July 19, 1999 7:38 PM To: 'Marc Silver'; 'freebsd-questions@freebsd.org' Subject: RE: DoS?? 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.
