It's OK because the OS is using over 800MB of memory for disk cache - this is the typical behavior for RedHat. The OS uses free memory as a disk cache to increase IO performance and will give this memory up as applications need it.

The disk cache will take up ram, but be relinquished when other things need it (ie. it's as good as free memory, over 800meg of it in your case). The reason none of your swap is being used is because you do not in any way need it. Having zero swap usage is a very good thing, using swap instead of ram is a sign your machine is under-speced for the job. <A href="http://forums.gentoo.org/viewtopic.php?t=175419">http://forums.gentoo.org/viewtopic.php?t=175419</A> provides a reasonably concise overview of the problem here. simon ----- Original Message ----- From: ram <<A href="mailto:talk2ram@gmail.com">talk2ram@gmail.com</A>> To: Red Hat Network Users List <<A href="mailto:rhn-users@redhat.com">rhn-users@redhat.com</A>> Sent: Tuesday, July 4, 2006 8:41:55 AM GMT+0000 Subject: [rhn-users] Hi Memory consuming High Hi all I have just installed RHEL ES 4, with everything option and disabled all the services, except my requirement when i see free i have found most the RAM free 80% of 1GB RAM after some time when i transfer data from another server to this server 95% RAM FULL, is this something wrong with the RHEL ES Bugs ? what is the tools to check and free the RAM i have installed PIII Server with 1GB RAM. how would i use SWAP instead of RAM. when iam using any application most of the time my Swap is not at all used [root@mail ~]# free total used free shared buffers cached Mem: 1034148 1018396 15752 0 35928 869036 -/+ buffers/cache: 113432 920716 Swap: 1048568 0 1048568 ram -- Simon Elliston Ball Infrastructure Manager Cromwell Business Systems This email is sent on behalf of Cromwell Business Systems Ltd. and is strictly confidential and intended solely for the addressee(s).
