Hi,

just to give a status followup:

I should apply for the JREF Million Dollar Challenge with this level
of correct prediction of the future:

nexus#sh track
Track 1
  Response Time Reporter 1 reachability
  Reachability is Up
    1 change, last change 4w3d
  Latest operation return code: OK
  Latest RTT (millisecs) 1
  Tracked by:
     applet duck-reachable

Since I hacked in the EEM applet, it never triggered. In a way this is
good (I finally can sleep through again), but then again, what's wrong
now for the bug to no longer trigger?

1) It's a real Heisenbug that vanishes as soon as someone watches closely;
2) It actually *was* a problem with the replaced power supply;
3) It was an issue with a BRI interface that had a bad BRI connected which
   was constantly triggering PHY errors.

To give (1) a chance, I'm posting here, maybe it tickles Murphy just like
it did for Ed ;)

But seriously I'd rather focus on (2).

HTH,
Andre.
