At the rabbit erlang prompt, evaluate
   memsup:set_sysmem_high_watermark(0.01).
to lower the memory threshold. You should see a message
   alarm_handler: {set,{system_memory_high_watermark,[]}}
appear in the rabbit.log.

To raise the threshold again, evaluate
   memsup:set_sysmem_high_watermark(0.95).
at which point you should see
   alarm_handler: {clear,system_memory_high_watermark}
in the logs.
