14 == EFAULT. Those are generated when the kernel tries to write out a process's memory image for a coredump and the indicated range of memory couldn't be faulted in so that it could be written to the filesystem. > What does this indicate?

The inability to fault in memory that the kernel thinks should be there makes me wonder if you're swapping and the device you're swapping to is failing. Your dmesg suggests you might be swapping to your CF card and you (only?) have 128MB of real memory. When this is happening, what's the output of "swapctl -l"? If that shows you are indeed into swap, then a failing CF card would be my guess. (Swapping to CF seems like a bad idea to me, but I'm not expert in that sort of hardware...) Philip Guenther
