May be... (I've no idea if apache buffers data to disk) but this is only accidentally correlated with the *number* of internal servers. In fact, it's just a question of traffic. I'm assuming that the questioner can calculate traffic - but he seems concerned that if he adds too many ProxyPass lines to the config, that he'll get an error saying "Too Many Proxies Configured! Overload! Overload! Overload!..." He won't.
