swainfo and memory usage issue...

Hoang Chi Cong_1 — Wed, 21 Sep 2005 22:22:03 GMT

Dear all,
I have to face a trouble: current, my system's memory is always almost used.
I check in glance for a few days and the usaged very hight:
Mem Util ......... 95% 97% 100%
Swap Util ......... 80% 85% 95%

The out put of swapinfo:
Kb Kb Kb PCT START/ Kb
TYPE AVAIL USED FREE USED LIMIT RESERVE PRI NAME
dev 8388608 1015236 7373372 12% 0 - 1 /dev/vg00/lvol2
reserve - 6758764 -6758764
memory 12237992 7759204 4478788 63%

The total of RAM in my system is 16GB:
(here is from cstm)
Basic Memory Description

Module Type: MEMORY
Total Configured Memory : 16384 MB
Page Size: 4096 Bytes

Memory interleaving is supported on this machine and is ON.

I think there is something wrong when setting for memory.
Could someone give me some advice?
What should I do?
Do I have modify any kernel parameter?

Any device will much appreciated!

Regard,
Hoang Chi Cong

Hi,

Allthough the memory is 16Gb the primary swap in only 8Gb. Is it done intentionally ?

Please post
#swapinfo -atm

Also what is the application running on the system? Even in this scenario if everything is running fine and processes does not go out of memory then everything should be fine but you should plan for memory upgrade.

HTH,
Devender
