Yes, I know you are running on PPC64, but that doesn't tell me
anything about the hardware you are running on. How many CPUs, how
much RAM, what storage you are using, how it is configured, etc, is
the sort of infomration relevant to understanding the circumstances
around the failures you are seeing...
