Probably what is happening is that in the middle of the night, your distribution runs a cron job like "slocate" or "medusa" which scans through your hard drive. Other distros do security checks for world-writable files and many other things... This heavy read activity fills up a lot of buffers and causes your apps to be swapped out.
