Re: Another Odd (not documented) problem with 1.NOVM.21

If the size of the cache_object you are retrieving exceeds a certain
size (I used to think that that size was the value of cache_mem, now I'm
not so sure) then yes, go boom.

It's on my personal hunt-list, but I've never quite gotten to it. I
think it's a low priority bug as far as they go.
