The above message contained the following:

And, apparently, only on your machines. I haven't heard of anyone else
having this problem.

"Inconclusive" is, indeed, the operative word.

Not necessarily. The LDM makes much greater use of memory-mapping,
semaphores, locking, I/O, signals, etc., than the vast majority of other
applications. So the absence of crashes by other applications doesn't
rule-out problems with the operating system or hardware. Until we
pin-down the problem, I'm not ruling anything out.
Keep an eye on Ernie (I'm watching it here).
