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.
