Also, by adjusting this, would I possibly just be delaying the problem we currently have (i.e. over time, we start to run out of memory)? I just wonder why the system is reaching this limit at all... do you feel it is quite normal for a system with this memory configuration to be configured with the ratio set to 80? I'm not terribly familiar with these VM parameters, so I apologize if I sound vague.
