In this case, I have to cycle the power. Sounds more like a hardware problem to me, possibly overheating from doing lots of I/O to disk and burning a DVD at the same time, or maybe just straining the power supply enough to trigger a crash from sagging voltage. > What can I do to figure out what is going on? If you up the verbosity level of samba's logging using the -d flag to smbd, (by hand, via /usr/local/etc/rc.d/samba.sh, samba_flags in /etc/rc.conf or some such), you can get vast quantities of logging info from Samba. But I suggest first looking through your existing Samba logs and other messages under /var/log, and see what's there now. To determine whether it really is Samba causing the problem, or something else, stop samba, and try doing something like: while true; do du -a / > /dev/null done ...for a few hours to generate a solid load on your hard drive(s). Then try burning a DVD while that command is still running, and see whether you get a system crash or lockup. -Chuck PS: Also see "man crash" and the handbook.
