From painful experience: Sometimes GFI breakers just go bad. (The pain came
when it tripped when I was shaving and the electric shaver grabbed a few
gazillion whiskers when it stopped). Replaced the GFI breaker and no further
problems. (Also switched to a rechargable razor )

I agree with Doug, whenever I've had intermittent tripping of GFCI
breakers, its always turned out to be an outside outlet with water
getting in. Also I'd question a central vac that's not on a dedicated
circuit. The ones I've wired require a 20 amp circuit by themselves

That's what I thought too, and the code here probably requires it. I
didn't install the vac though, and it might have been ok all those years
ago. I'm not positive about the exterior outlets and I didn't remove them
to check because they are sealed with caulk. The seal looks good but I
guess this summer I know what I'll have to do.
