From the vector 670 ( = processor incorrectable error) and the previous messages, I suspect you have bad memory. I suspect the correctable errors are memory corruption errors which can be fixed by the ECC bits, and the panic is corruption so bad that it cannot be fixed by the ECC bits. Try yanking simms until the errors stop. Of course, it could also be a problem with the motherboard (bcache) or the CPU (icache/dcache).. You might also try to remove any excess dust buildup & make sure the box is properly cooled. Good luck, Drew ------------------------------------------------------------------------------ Andrew Gallatin, Sr Systems Programmer http://www.cs.duke.edu/~gallatin Duke University Email: gallatin@cs.duke.edu Department of Computer Science Phone: (919) 660-6590 To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-alpha" in the body of the message
