Stephen, Thanks for the explanation.I'm using Suse 10.0
Its a bit different coming from a windows background - you can view all the processes and see where all the memory has gone. I thought I had a problem when I added up the memory used from the processes and it only came to a fraction of the total memory used, and then I saw my free memory dropping like a stone :) btw - my top looks like: Mem: 1034548k total, 990596k used, 43952k free, 57616k buffers On 4/24/06, Stephen John Smoogen <[EMAIL PROTECTED]> wrote: > You dont mention which Unix you are using, but with Linux the kernel > will cache data in memory until about full. this means that emails > that have long queues and such will not seek to disk as often and > stuff like that.
