      I've seen a situation where the wiredTiger.engineConfig.cacheSizeGB was set to  200453 by mistake. This is equivalent to 200TB. I believe this exceeds the maximum value anyway, but it caused unexpected crashes. 

      Can we add a startup warning when this value exceeds the maximum value to try and catch this earlier?
