Each system has been installed with FreeBSD 6.1-RELEASE. Exim 4.63 and Spamassassin 3.1.4 have been installed from source, not ports. The systems are used as inbound e-mail/spam scanning gateways. Periodically, usually between 2 and 10 days of uptime, each of the boxes crashes with a "Fatal trap 12: page fault while in kernel mode" error. The crashes have occured using a custom SMP kernel (unused device drivers removed), a GENERIC-SMP kernel and a GENERIC kernel. Crash message from custom SMP kernel:- Fatal trap 12: page fault while in kernel mode cpuid = 1; apic id = 06 fault virtual address = 0x5c fault code = supervisor read, page not present instruction pointer = 0x20:0xc0578f90 stack pointer = 0x28:0xe8918b10 frame pointer = 0x28:0xe8918b2c 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 = 15752 (exim-4.63-3) trap number = 12 panic: page fault cpuid = 1 Uptime: 6d5h7m32s Cannot dump. No dump device defined. Automatic reboot in 15 seconds - press a key on the console to abort Crash message from GENERIC-SMP kernel:- Fatal trap 12: page fault while in kernel mode cpuid = 1; apic id = 06 fault virtual address = 0x5c fault code = supervisor read, page not present instruction pointer = 0x20:0xc06eefd4 stack pointer = 0x28:0xe8df6b10 frame pointer = 0x28:0xe8df6b2c 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 = 54198 (exim-4.63-3) trap number = 12 panic: page fault cpuid = 1 Uptime: 2d13h27m51s Cannot dump.
