HI, We have a linux AS3 on a server with 4 GB RAM 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 Any pointers would be appreciated regards -- redhat-list mailing list unsubscribe mailto:redhat-list-request@xxxxxxxxxx?subjecthttps://www.redhat.com/mailman/listinfo/redhat-list
