I am running rabbitmq as a cluster node, the version 2.8.2, erlang info:
Erlang R15B01 (erts-5.9.1) [source] [64-bit] [smp:8:8]
[async-threads:30] [kernel-poll:true]

The system is Ubuntu server 9.10 64 bit.

This rabbitmq has been running for long days without problems.
Today I restarted it but failed. The info:

root at rabbitmq2:/var/log/rabbitmq# cat startup_err

Crash dump was written to: erl_crash.dump
eheap_alloc: Cannot allocate 2850821240 bytes of memory (of type "heap").

Status of node 'testmq-slave at rabbitmq2' ...
Error: unable to connect to node 'testmq-slave at rabbitmq2': nodedown


nodes in question: ['testmq-slave at rabbitmq2']

hosts, their running nodes and ports:
- rabbitmq2: [{rabbitmqctl4487,63660}]

current node details:
- node name: rabbitmqctl4487 at rabbitmq2
- home dir: /var/lib/rabbitmq
- cookie hash: ****

As you see, my system has enough free memory, but rabbitmq aborted in
the process of starting.
Please help, thanks in advance.
