I\'m pretty certain this is a bug, but it seems to have no detrimental effects besides an annoying message. I\'ve seen posts from people claiming that they\'ve allocated, like, 32GB of RAM to the game and still get the message. Alternatively you might not have enough RAM allocated, so if you\'re having some kind of issue that might be related to RAM usage, try what MichaelSeph suggested and it may help. Otherwise it probably won\'t hurt to just ignore it.
