[rabbitmq-discuss] 2.7.1 / R14B04 Crash Report: ~1PB RAM allocation failure

[Gavin M. Roy]

I had a fun crash this morning on a production machine. Notice the amount
of memory trying to be allocated? Is there anything the RabbitMQ dev's
would like? The full erl_crash.dump or core file (6.4GB) -- I'd prefer to
send those off list.
