So let's see what happens tonight... Looking at your other post, it seems that some process is requesting a bunch of memory during the night, and the kernel kills the most memory consumer ones to make room for the new one (and according to other criteria). I had this exact same behavior when a rsync-based backup was running overnight: it was listing files from an enormous disk, the amount of memory for this was huge and firefox and other big memory eaters being killed nearly every night.
