When I rebooted my server, swap went down to less than 1%. The swap usage has been increasing steadily everyday. I run 6 websites on the server, 2 are forums, 1 of them uses Xoops. When I type top -c Sort by memory usage, I see many mysql processes. Anyone know what's going on? My server's swap usage is always under 1% before I upgraded Php and MySQL to the latest 4.x versions.
