Typical.  The old saw about a watched pot...

With sensors output in a loop piped to a log file and tee'd to a window on
the
backend and top running in another window on the backend, I ran it all
evening
without a hiccup.  Enjoyed the movie, too. ;-)  I guess I could try backing
the
cooling fans down from tropical storm speed (as opposed to hurricane force
or
balmy breeze) and see if I can exacerbate the problem because at this point
I
have no breadcrumb trail, unless the details above are more significant to a
trained eye than they are to me.

Any advice welcome.  I won't post on this again unless I find something that

looks significant or someone suggests something to look at and report back
on.

Craig.
