Over time the memory Page Cache usage maxes out and doesn't come down until after a reboot. My server is a dual core AMD proc with initially 2GB of RAM. I was consistently getting seeing this happen and there would be poor performance until the server would lockup, giving a kernel out of memory error at the console. I searched around and saw that maybe I needed more RAM, so I purchased 8GB and put that in there. I'm still seeing the issue and poor performance on my media servers within a week's worth of usage. I don't think it's completely locked up with the kernel error since the RAM increase though. At this point I'm maxed out on the memory I can put in the box. Any suggestions?
