Hi list, We have a AMD with RHEL4 64 installed and the Oracle 10g installed as well. It has the latest kernel update 2.6.9-42.0.8.ELsmp but the memory is always being used by some unexplained processes. There are 4 CPUs, 16 GB RAM, 33GB swap but memory used = 16148872k Even when oracle is shutdown, a memory use is still nearly 16GB. CPU is 99.4 % in idle, and I/O is too quiet. This is quite difficult to explain. Could anyone have any idea ? Here is the display of the top command top - 14:57:33 up 30 days, 22:29, 3 users, load average: 0.22, 0.10, 0.02 Tasks: 121 total, 1 running, 120 sleeping, 0 stopped, 0 zombie Cpu(s): 0.0% us, 0.0% sy, 0.0% ni, 99.4% id, 0.6% wa, 0.0% hi, 0.0% si Mem: 16360260k total, 16198280k used, 161980k free, 256496k buffers Swap: 33551744k total, 186960k used, 33364784k free, 14973940k cached vmstat 2 procs -----------memory---------- ---swap-- -----io---- --system-- ----cpu---- r b swpd free buff cache si so bi bo in cs us sy id wa 0 0 186960 161420 256496 14973940 0 0 1 112 3 1 0 0 99 1 0 0 186960 162284 256496 14973940 0 0 0 170 1021 2162 0 0 100 0 0 0 186960 162276 256496 14973940 0 0 0 44 1009 2149 0 0 100 0 0 0 186960 162284 256496 14973940 0 0 0 42 1008 2244 0 0 99 0 0 0 186960 162292 256496 14973940 0 0 0 48 1011 2164 0 0 99 0 0 0 186960 162292 256496 14973940 0 0 0 56 1006 2118 0 0 100 0 0 0 186960 162292 256496 14973940 0 0 0 66 1011 2154 0 0 98 2 cat /proc/meminfo MemTotal: 16360260 kB MemFree: 162740 kB Buffers: 256496 kB Cached: 14973940 kB SwapCached: 9724 kB Active: 2709340 kB Inactive: 12799980 kB HighTotal: 0 kB HighFree: 0 kB LowTotal: 16360260 kB LowFree: 162740 kB SwapTotal: 33551744 kB SwapFree: 33364784 kB Dirty: 332 kB Writeback: 140 kB Mapped: 1147256 kB Slab: 608056 kB CommitLimit: 41731872 kB Committed_AS: 7853044 kB PageTables: 39080 kB VmallocTotal: 536870911 kB VmallocUsed: 16760 kB VmallocChunk: 536854071 kB HugePages_Total: 0 HugePages_Free: 0 Hugepagesize: 2048 kB ____________________________________________________________________________________ Never miss an email again!
