[rabbitmq-discuss] RabbitMQ 3.2.4 crashes - std_alloc: Cannot allocate 1125562100111744 bytes of memory (of type "arg_reg")

[Oskar Liljeblad]

Hi!
That was in a different cluster, and we solved that problem by not mirroring some queues (!).
The new crashes occur on a standalone node. Just need to know how to enable debugging.
I'm not familiar with Erlang debugging in general, but if you'd tell me to run rabbitmq-server in gdb, recompile etc I'd probably know what to do.

Regards,
Oskar

You asked the same question back in September: 
http://rabbitmq.1065348.n5.nabble.com/RabbitMQ-3-1-5-crash-Cannot-allocate-1124815738393216-bytes-of-memory-of-type-quot-arg-reg-quot-td29326.html

No new data has come to light since then to help us debug this.

Is there anything noteworthy in RabbitMQ's log files?
