The fifth colums gives the memory, right? Should this add up to the total of the 'used' column in free -m? Because it does not: wonko@weird ~ $ free -m total used free shared buffers cached Mem: 3452 3117 334 0 39 279 -/+ buffers/cache: 2798 653 Swap: 4094 1472 2622 wonko@weird ~ $ total=0; for rss in $( ps aux | grep -v USER | awk '{print $6}' ); do (( total += rss )); done; echo $(( total / 1024 )) 1984 So, I get a sum of around 2 G with ps, while free -m shows 4.5 G. Whoops? Am I missing something here, or does it look like lots of RAM is not being freed? Wonko
