Hi,

top OR (if you have) glance is good tool to root cause of excessive memory utility in your system.

first you have to find what process are eating memory:
# top
and use ps command to get more information about process.
# ps -ef |grep

Even if no applications are running by default OS creates some processes. As suggested in the earlier responses you need to figure using TOP and GLANCE which of those processes are consuming so much memory.

Re: Memory Utilisation is very high in 11.31

lower the kernel values for the parameters,

filecache_ min and filecache_max ,

high values of filecache_max (default 50 %) may be the one tends to display to hig utilization for memory..

Hi,


From my experience anything between 3 to 5GB memory utilization for an idle system(11iV3) is normal.

Thanks!
