There has been many various improvements on that front:
* RabbitMQ's memory consumption has been studied closely, bringing many fixes in autopkgtest-cloud.
* We have a watchdog restarting RabbitMQ when things go bad.
* This watchdog has been exercised a lot before the memory consumption fixes and the code is able to deal with a RabbitMQ restart correctly.
