[rabbitmq-discuss] RabbitMQ 3.1.5 crash: Cannot allocate 1124815738393216 bytes of memory (of type "arg_reg").

[Oskar Liljeblad]

I restarted the service but I see the usual log messages regarding accepted and closed AMQP connections - now only in /var/log/rabbitmq/startup_log (which I assume is stdout) rather than /var/log/rabbitmq/rabbitmq at instance.log

Regards,

Oskar

Many thanks. I will give it a try and let you know if it crashes again.

Regards,

Oskar

An opinion offered on the erlang-questions mailing list about a similar
question suggests that the error logger is responsible for attempting
the allocation:
http://erlang.org/pipermail/erlang-questions/2012-May/066600.html

I hesitate to suggest this for a production environment but try turning
logging off to see if that helps.

Change "'{file,"'${RABBITMQ_LOGS}'"}'" to "false" and
'{file,"'${RABBITMQ_SASL_LOGS}'"}' to "false" in
/usr/lib/rabbitmq/bin/rabbitmq-server.

If that cures the problem then we'll need to find a way of determining
what the original error was that triggered the large error message.
