Bad RAM, perhaps? Or other hardware dying?
As to RAM, how can I test it? http://www.memtest86.com/ seems
to be for Intel architectures only.
I wish I knew.
I guess this need not be a linux-specific test. Checking the RAM
with TechTool from MacOS X would do the job, too, right? (Dumb
question, I know, but I want to be an the save side...)
TechTool should give the RAM a workout. It may work for disk too.
Also, Linux itself is a pretty stiff RAM workout. I've heard it said
that a Linux kernel build will find RAM problems faster than any
commercial test -- it's just that the diagnostics are less specific as
to the exact cause of the failure.
My advice: If you suspect a flakey RAM, try to find something (or a
combination of somethings when run simultaneously) that tickles the
problem reliably (it may involve running a suite of programs for a few
hours before it breaks, but it should reliably break eventually). Then
open the box and remove one RAM SIMM and try again. If it still fails,
replace the SIMM and remove a different one. Repeat this process until
the problem disappears. Once you are certain that you have found the
bad SIMM (e.g. put it back in and verify that the problem returns)
physically destroy it so that nobody can ever try to use it again! I
find that pounding on it with an appropriately sized hammer is
effective -- and a good way to relieve the accumulated stress the @#$%
thing has caused me.
