Not sure about the former; seems unlikely, since we're talking about usage patterns and data that have not changed. Most likely a recent software update from testing... but what? I've killed every daemon I know it's safe to on the box.
You can make it swap more by vm.swappiness=90 in sysctl.conf. Or # sysctl vm.swappiness=90 at the command-lineThis doesn't actually make it swap more, but it tells the kernel to swap more if it's running short of RAM. This will put unused daemons, etc. into swap, freeing memory. (or just free the memory as executables are demand paged anyway)
A lot of Pi people seem to like setting that to 1 to try to minimise swap usage (and hence SD card wear - I set it higher to deliberately free up more RAM and my Pi's running better - or at least it seems that way to me.
