Is this a plug-in breaker, or one that's wired in?
It is a GE "snap in" breaker in a GE breaker panel (load center).
The breakers have fingers that grip a bus bar in the panel, and a screw
terminal that holds the wire.

In either case, it seems possible that its connection to the wiring
has deteriorated (oxidized, worked loose, etc.) and it might be
heating up at that point. If your home has any aluminum wiring, I'd
be _very_ concerned about this possibility.

No, NO aluminum wiring! I checked before buying!

I'd recommend a full re-check, with the mains power entirely
disconnected.
The fact that after resetting, the breakers are now running cool tells me
the contacts have been cleaned by cycling them, and should be OK for the
next 10 years or so.
