I left my desktop running for a couple of days, and swap usage has slowly been growing - just before I rebooted just now it was at 2.1GB, and the whole GUI has slowed down. After reboot, my swap was not used, and only about 400Mb of main memory. How can I find what is using swap, to get a clue as to what it is. -- Alan Chandler http://www.chandlerfamily.org.uk
