[rhn-users] Physical memory becoming low

[d.qureshi at mdx.ac.uk]

Hello,

I am currently running the following operating system on HP Proliant DL380 server:-
Red Hat Enterprise Linux AS 4 (Nahant Update 3).

The HP Proliant DL380 server has 3Gb of main memory in it.
I have noticed the memory is becoming very low.

When I do a vmstat -s the total memory is 3115272K and the used memory is 3096768K. The server has an Oracle database
which has been allocated 300Mb of memory for expansion which is very low.

Can anyone tell me what else I can do to find out what is causing the memory to become low and how I can fix 
the low memory problem?

Regards,
Dan..
