Unfortunately, from experience, no moving parts (if that's what you
mean my solid-state; if not, disregard the rest of this mail :) )
doesn't equal non-failure. Just a bit less likely to fail. PSUs still
die on you, capacitors still "blow up", microchips still get fried if
not properly cooled, flash memory "wears out" etc.

I've had all sorts of switches die on me in strage ways, a couple of
them the same way it happened to you (they suddenly refused to switch
packets).

Currently I'm in the middle of replacing three ProCurve switches
(oldest one bought within a year) because the NVRAM became read-only
all of a sudden. I really hope the service guys will be able to tell me
what happened (if it was an environment issue, firmware bug, a bad
batch of chips...).
