Here's the output of the panic. It hung again while dumping core... Fatal trap 12: page fault while in kernel mode cpuid = 3; apic id = 02 fault virtual address = 0xa748d260 fault code = supervisor write, page not present instruction pointer = 0x8:0xc060b611 stack pointer = 0x10:0xe971bc20 frame pointer = 0x10:0xe971bc20 code segment = base 0x0, limit 0xfffff, type 0x1b = DPL 0, pres 1, def32 1, gran 1 processor eflags = interrupt enabled, resume, IOPL = 0 current process = 52 (swi6: task queue) trap number = 12 panic: page fault cpuid = 3 boot() called on cpu#3 Uptime: 5d6h6m34s Dumping 3967 MB 16 32 48 64 80 96 112 128 144 160<hang> Whenever it panics it will hang at a random point during the dump, this last time was the farthest it got... Someone seems to suspect bad ram as the culprit. I can always swap it out and see what happens. -Hogan On Wed, Nov 24, 2004 at 11:24:43PM -0800, Doug White wrote: > On Tue, 23 Nov 2004, Hogan Whittall wrote: > > > Dell PE6450 server, 4xP3-700 Xeon, 4gb ram, system disks reside on > > a 2 disk RAID1 attached to a MegaRAID controller.
