I actually have disabled the swap partition (!) since the system goes really bad and based on my experience I have to enter the room and reset the affected machine (!). Otherwise I have to wait for long times to see it get back to normal.
When I ssh to the node with root user, the ulimit -a says unlimited virtual memory. So, it seems that the root have unlimited value while users have limited value.
