Nope. If you have previously used more ram, some processes are paged
out. They are not paged in again just because there are free memory.
They are only paged in when those pages are needed.

I think there is a bug somewhere in the system. I have problems with the
machine hanging if it's heavily used for a while. Processes seem to be
waiting for I/O which never completes. I think it's connected to paged-out
processes as well...
