The problem I have with troubleshooting intermittent failures is that
they are only intermittend sometimes.

Yes, it may be hard to replicate but you just have to try and try
again sometimes.  Or create something that exercises the unit or
software to make it happen and automatically catch it in the act.

I don't care to have to do that very often.  When I do, I just try to
make it a challenge.
