This has probably been discussed before, so apology for asking the same question again. Should the Active memory, as reported by top(1), be equal to the sum of rss (the real memory (resident set) size of the process) of all processes, as reported by ps(1)? The sum of ps(1) rss fields is probably the same as the sum of RES fields of top(1). I seem to have much bigger Active set than the sum of all resident (or real) memories used by all processes. Please advise many thanks anton -- Anton Shterenlikht Room 2.6, Queen's Building Mech Eng Dept Bristol University University Walk, Bristol BS8 1TR, UK Tel: +44 (0)117 331 5944 Fax: +44 (0)117 929 4423
