Is it normal that inactive memory are not recycled back to unused memory in Red Hat Linux after a long period of time (i.e. after a week)?
I'm using Red Hat Linux Enterprise 2.4.9-e.25enterprise with 4G RAM and running a Java server application that consumes around 22% RAM resources (I used top to monitor this). While conducting stress tests on the server app, the RAM memory usage grew to around 50%. After shutting down the server app, the memory used is still around 50%. Here's a snapshot of the /proc/meminfo:
total: used: free: shared: buffers: cached: Mem: 4217606144 2042474496 2175131648 0 177762304 1692585984 Swap: 2147467264 0 2147467264 MemTotal: 4118756 kB MemFree: 2124152 kB MemShared: 0 kB Buffers: 173596 kB Cached: 1652916 kB SwapCached: 0 kB Active: 1375916 kB Inact_dirty: 450580 kB Inact_clean: 16 kB Inact_target: 1029612 kB HighTotal: 3276720 kB HighFree: 1913444 kB LowTotal: 842036 kB LowFree: 210708 kB SwapTotal: 2097136 kB SwapFree: 2097136 kB BigPagesFree: 0 kB
Any constructive advice/tip will be greatly appreciated. Thanks!
