This _must_ be one of your swap drives, and the swap drive must be big enough to have the content of your physical memory dumped onto it. To enable it without rebooting, use dumpon(8). After that, when your machine crashes, the crash dump will be saved into /var/crash when it comes back up, along with a copy of the kernel which generated it. These can be inspected later with `gdb -k'. If this happens a lot, you should generate a debugging kernel with `config -g'. Check the handbook, section ``Debugging a Kernel Crash Dump with KGDB'' for more info on all of this. hometeam@techpower.net --We cannot all be masters, nor all masters Cannot be truly follow'd-- -----BEGIN PGP MESSAGE----- Version: 2.6.2 owEBqwBU/4kAlQMFADRCxNWhsddKSTR+6QEBelED/jzeC3btZfqSdIfrNoCgwUJJ iNQ33UQoMyJ2ygkfl72xP5J79yml/F4P73GnNaDVbaMOmOG2NNAi5ElE73wRh54U 17kH+n5XnYeqekV8T2TG2Q6ex3UotXPyZ1vvrCrSxapOz6a4hh0GQeA55rcwLy2W ROHwxfvaVsrX5iVOkRoerBFiC21lc3NhZ2UudHh0AAAAAA== =jCvF -----END PGP MESSAGE----- On Wed, 9 Dec 1998, Robert Blayzor wrote: > cvsup'd from my 2.2.7-stable to my 2.2.8-stable and now my machine > mysteriously reboots after a few minutes. > > I did a buildworld, installworld, reboot, built ner kernel, reboot. > > The machine is a P2 400 w/256MB of RAM... > Runs Dnews... > > Any ideas? > > There are no messages in /var/log/messages when it reboots and nothing > on the console. > > -- > Robert Blayzor robert@superior.net Telecon Communications > MIS/Programmer/Admin Network Engineer 131 Enterprise Rd. > Superior Net Services 518-762-3456 Johnstown, NY 12095 > "FreeBSD!
