These systems were on a home cable modem connection and there were pretty regular break-in attempts. When reviewing logs, I'd see attempts to brute-force logins and passwords for the ftp and ssh services. I eventually had to turn ftpd off since it seemed guaranteed to panic the box during one of these cracking attempts. sshd seemed to handle things better, but I have had one panic occur. I haven't tried 6.2 to see if I encounter similar problems. -Damian
