A RabbitMQ customer claims to have reproduced this error even after
disabling logging. (The thread from the rabbitmq-discuss mailing list
starts here:

The error is:

Mon Sep  9 12:01:31 2013
Slogan: std_alloc: Cannot allocate 1121150602465920 bytes of memory (of
type "arg_reg").
System version: Erlang R16B01 (erts-5.10.2) [source] [64-bit]
[async-threads:30] [hipe] [kernel-poll:true]
Compiled: Sun Jul  7 05:35:15 2013
Atoms: 27430

Is there anything that can be done to avoid errors like this?
Is there any way of determining what the original error was that
triggered the crash?
