If you're getting near the memory limits then yes, there should be
entries in the logs.
Note that Rabbit basically assumes it's going to have 80% of the
machine's RAM available for itself. If that's not the case, you need to
reduce the memory high watermark - see
However, you should also be able to see what's going on by inspecting
the state of the queues with rabbitmqctl list_queues (though see man
rabbitmqctl for other things you might like to monitor). Unless you've
basically got almost no free memory left by the time you start using
Rabbit, it should be fairly hard to make rabbit crash.
And it's extremely unlikely Rabbit is crashing without putting out some
sort of crash report somewhere.
