Random resets on some energy meter firmware: Client reports tens of minutes to hours apart. This sort of thing can be a devil to reproduce. I've got the in-circuit debug pod attached and some breakpoints set in the places the code might go down to get a reset, I'm also running the communications link (Modbus RS485) fairly hard just to try and provoke it a bit. More or less what the client had set up.

Now just have to wait for it to (hopefully) stop on one of the breakpoints. Then I get a snapshot of the internal RAM and registers. I think I know what the cause is but I need to prove it.
