I'm no kernel hacker, but it really sounds like some kernel data structure is getting hosed. Perhaps the filesystem on which the news resides is corrupted and causing junk pointers to be thrown around the place? This is really a bit of a wild guess, but if you can newfs the disks it's probably worth trying. Another possibility is that your RAM is bad.. have you tried replacing it? Niall -- Niall Smart.
