On a Red Hat 3.2 system running Sun Directory Server Sun DS had a virtual memory failure and hung while I was running a system stress test. The test involved running 30 DS entry scans. I noticed that the steady-state memory behavior of the system leaves only 1% or less of the system memory in the free pool: eds2:/root] # vmstat 1 procs memory swap io system cpu r b swpd free buff cache si so bi bo in cs us sy wa id 0 0 0 115600 273828 5364176 0 0 0 2 1 2 0 0 0 3 0 0 0 115600 273828 5364180 0 0 0 52 191 142 0 0 0 100 0 0 0 115600 273828 5364180 0 0 0 0 178 134 0 0 0 100 0 0 0 115600 273828 5364180 0 0 0 0 180 111 0 0 0 100 Most systems I am aware of recommend 10%-15% of memory on the free pool as a low-water mark. I think I need to set the steady state free pool at ~10%. Am I on the right track ? How do I do this ?
