What is node1 doing? Are publishers connecting to it? If so the memory
might simply be taken up by message backlogs, i.e. the producers are
producing messages at a faster rate than rabbit can sustain. Eventually
this would result in a memory alarm and producer connections getting
blocked until the backlog has been reduced.
