[rhn-users] Physical memory becoming low

[Lamon, Frank III]

run the "free" command and see how much is being used as cache. Linux
will use free memory as cache by default to help improve performance and
will give it back as needed by the OS and apps.

Here's some info: http://www.redhat.com/advice/tips/meminfo.html

Subject: [rhn-users] Physical memory becoming low


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..
