Hi all. I have a basic question i am getting a lot of spin on. Looking at this output from top it would seem obvious that this server is overloaded seeing how it has 0 cpu load and 95% memory usage. My admin told me its fine because it has quite a bit of cache. Cpu(s): 0.0%us, 0.0%sy, 0.0%ni, 99.8%id, 0.0%wa, 0.0%hi, 0.0%si, 0.0%st Mem: 6105732k total, 5769024k used, 336708k free, 97040k buffers Swap: 2031608k total, 24744k used, 2006864k free, 1368728k cached I can understand that the cache can be freed easily if needed but the basic poll I am trying to take is. Is this server ok or not and how best to reply to the "it has cache" answer if not. Thanks
