No swap yet. =09But the sum of RSS column of "ps axum", gives me about 600MB used. =09I know that kernel allocated memory doesn=B4t show in ps, but I think it=B4s not using 1.4GB. =09The head of top is like this: last pid: 7323; load averages: 1.49, 1.11, 1.30 up 4+05:57:30 19:01:= 05 184 processes: 1 running, 183 sleeping CPU states: 16.7% user, 0.0% nice, 3.5% system, 0.6% interrupt, 79.3% id= le Mem: 333M Active, 1218M Inact, 157M Wired, 42M Cache, 112M Buf, 256M Free Swap: 8192M Total, 8192M Free =09Also, why there is a difference between free memory reported by top and vmstat? =09Could it have some memory leak? Is there any report of it in freebsd 5.x? Thank you, - Marcelo
