[rabbitmq-discuss] RabbitMQ memory limit and shutting down

[Nikita Trophimov]

Hello everyone.
Recently, I tried to check RabbitMQ in some critical situations, and 
found that if it doesn't have enough memory it will be turned off 
without subsequent restart. We need to create a stable system, so I'm 
wondering if we can do anything in this kind of situation (maybe more 
frequent garbage collector calls, certain configuration, etc).

Here's what I found in the logs:
