About once a day the machine crashes with the following in the message log:

/kernel: Fatal trap 12: page fault while in kernel mode
/kernel: fault virtual address   = 0x46
/kernel: fault code      = supervisor read, page not present
/kernel: instruction pointer = 0x8:0xc0200960
/kernel: stack pointer           = 0x10:0xd6a43c28
/kernel: frame pointer           = 0x10:0xd6a43c18
/kernel: code segment        = base 0x0, limit 0xfffff, type 0x1b
/kernel: = DPL 0, pres 1, def32 1, gran 1
/kernel: processor eflags    = interrupt enabled, resume, IOPL = 0
/kernel: current process     = 63563 (courieresmtp)
/kernel: interrupt mask      = none
/kernel: trap number     = 12
/kernel: panic: page fault

So after all hardware is upgraded, I assumed I wouldn't see the same crash, but I am. I've only ever seen it crash due to some issue with couriersmtp. I did

No matter what couriersmtp does or does not, it should not result in a kernel crash. This is a kernel issue. Nothing that a userspace application can do should result in a kernel crash.
