[rabbitmq-discuss] RabbitMQ 1.7.2 with Erlang R13B04 crashes after several hours running MulticastMain from 1.7.2

[John Apps]

Wondering why this crashes when vm_memory_high_watermark is set?

This message "vm_memory_high_watermark set. Memory used:935,079,976
allowed:858,993,459" is rather intriguing, or am I missing something? (The
commas were inserted by me in order to make the number more legible.)

Environment:

   - Windows 7 X64 (4GB memory)
   - RabbitMQ 1.7.2
   - Erlang R13B04

rabbitmq.config

[
  {rabbit, [{vm_memory_high_watermark, 0.4}]},
  {rabbit, [{memory_alarms, true}]},
  {mnesia, [{dump_log_write_threshold, 1000}]},
  {rabbit, []}
].


Running these two clients:

   - MulticastMain -y 0 -s 128 -e e -t fanout -r 1100 -f persistent
   - MulticastMain -x 0 -e e -t fanout -y 10 -n 500 -q 1000

The broker crashed with:
