While I have no idea what update was installed lately on your machine, I 
would suggest to disable swap. Unless you want to hibernate the machine, 
it shouldn't be really necessary with 4GB of RAM. Furthermore you could 
try to find out which application is using all your RAM. I'm not sure, 
but something like

htop -s PERCENT_MEM

could be a start to find the culprit. My guess would be flash.

IIRC, virtuoso-t is the database for nepomuk, i.e. desktop search.
