[rhn-users] Memory utilization 100%

[Margaret Doll]

  I believe I found your explanation on RH memory.

     What's happening here is that the large transfer is mostly  
ending up in the disk cache in ram. 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.

     http://forums.gentoo.org/viewtopic.php?t=175419 provides a  
reasonably concise overview of the problem here.

However,  the memory is not released when I want to write DVDs unless  
I reboot the system.
