[c-nsp] Self rebooting pix?

[Michael Malitsky]

We've had a few PIX-501s overheat.  No internal fans, so they are
susceptible.

We've also had one or two of these have problems with the power
connector.  It would boot and run, but slight movement of the power
connector on the box would cause it to loose connection momentarily and
reset.

In both cases, symptoms are similar to what you describe.

Sincerely,
Michael Malitsky
