Oh, look, I used > just under 1MB of swap! Weeee... It's actually not too difficult to load up your system to observe the swap being used. Just create a text file .. call it 'mybash', and put one line within it: 'my bash' ..you can do this with the following command: $ echo bash mybash > mybash Next open up a term and enter 'top' to be able to see your memory usage .. then open another term and type 'bash mybash' to start an endless loop of the mybash script. You'll see the swap get consumed eventually. At some point it will run out of memory and die on it's own. -- Psyche-list mailing list Psyche-list@redhat.com https://listman.redhat.com/mailman/listinfo/psyche-list
