Those pages will eventually migrate out to swap, and that's the best place for them. Right now, I see that this system has been up for 16 days and has ~270MB of swap used. I typically see ~500MB of swap used when the system has been running a while longer. -- Bob Nichols "NOSPAM" is really part of my email address. Do NOT delete it.
