So far the system has been running without any lock ups since very late
Monday evening -- we're now almost 48 hours on.
So far so good, but it's hard to be certain this is the solution, since I
could never prove it was the root cause.
For now I'm just continuing to test and build confidence level. More time
will make me more confident. Maybe a week or so....
