If you've uploaded your flash player recently - undo that and go back to the last working version you had.
If you've got lots of neighbors- you can try to delete them
Other thing you can try is just leaving your buddy list off. I know it stinks. I havent turned mine on in months - I literally cant b/c my whole computer freezes, but at least I can function in the game and I just meet all my friends in events.
Hope that helps.
