4) Corruption is seen only after a reboot, if the machines continue to
run corruption is never seen again, until another reboot.
This sounds like a hardware problem.... May be heat related or due
to a marginal power supply? Try using a beefier supply on one of
the systems or removing something to reduce load. Or increase the
load by making disks do lots of seeking while you are running unzip
and running other things at the same time. To isolate heat related
problems we used to blow cold air (or hot air) on suspected
components and see if the problem goes away or gets worse.
These machines are in a brand new data center with more than adequate
cooling and have very beefy power.
Best,
George
