Deep in the forest in the dark of night on Sun, Dec 23, 2007 at 23:43 with a cackle and an evil grin freebsd-questions-request@freebsd.org cast another eye of newt into the brew and chanted: > Date: Sun, 23 Dec 2007 08:43:13 -0500 (EST) > From: "Monah Baki" <mbaki@whywire.net> > Subject: Server crashes > Hi All, > I'm running a very old server (P3, dual 600Mhz, SCSI 9GB > harddrive).

Often that is memory related and compiling the OS and kernel is one of the best ways to find bad memory :-(. It puts a stress on the machine that few other things will. Someone else asked if you could ping the machine. I have found that even when a machine is literaly dead you can still ping it, as the NIC cards seem not to notice that everything else is dead. I don't consdier a returned ping to be a test of much of anything. Bill -- Bill Vermillion - bv @ wjv . com
