Sounds like a leaky application, but without more info, we can't help. To give a counter-example, here's a snapshot of my desktop system's usage (taken from top(1) ) Tasks: 302 total, 1 running, 301 sleeping, 0 stopped, 0 zombie %Cpu(s): 0.0 us, 0.8 sy, 0.0 ni, 99.2 id, 0.0 wa, 0.0 hi, 0.0 si, 0.0 st MiB Mem : 30096.1 total, 25727.6 free, 2156.9 used, 2211.6 buff/cache MiB Swap: 65536.0 total, 65536.0 free, 0.0 used. 27297.9 avail Mem While I have more memory than you do (32Gb as compared to your 24Gb), I have 302 processes running and only about 4Gb of memory in use. Of my 64Gb of swap space, /none/ is in use. My previous desktop system(s) had less processing power, less memory, and less swap space, and ran lively, without memory or response time problems. So, if you want help, how about providing some details. HTH -- Lew Pitcher "In Skills We Trust"
