At any point of time my Free -m Gives total of 4000 mb and used of 3900
and free 10 mb but my buffers/cache used is hardly 1000 mb and 3000 mb free
Whereas
the top always gives
mem used 4000 mb avg and used 3972
Going by bufffers/cache i shudnt be having memory issues BUT our server is
monitored and keeps throwing above 80% memory utilisation all the time
why is there a discrepancy between TOP and FREE and which shud be used
more definitely for memory analysis
and why do we get over 80% used all the time when buffers/cache is low all
times
Pls assist
