I also suspect a ram chip...
Since I can't open it by now, I'm gathering info for a sure shot

After a long rest, the O1 seems to boot normally, and suddenly, at warm
up, the garbage collecting starts again...

In my rather limited experience I've found that problems which manifest
themselves on warming up tend to be capacitors rather than ICs. These can
be hard to track down. They are not Osborne 1 related, but here are a
couple of links showing my experience with dodgy caps. In both cases the
machines worked ok until warmed up.
