See the savecore man page for details. > I've looked at the man page, but am still a little shady on how to use > "savecore". How do I execute it if I don't know when/how my kernel crashes? If you've got dumpdev set in /etc/rc.conf, the /etc/rc will use dumpon(8) to tell the OS to save a core image to that device when it panics, and will call savecore to check for such a dump and save it to /var/crash during the automatic reboot after the panic. You can set it in /etc/rc.conf and do the dumpon command by hand, and the next crash should leave you a core image in /var/crash. <mike -- Mike Meyer <mwm@mired.org> http://www.mired.org/home/mwm/ Independent WWW/Perforce/FreeBSD/Unix consultant, email for more information.
