I suspect the rabbit logs will show that an alarm was raised.

Rabbit's response to such an alarm is to block all publishers, since 
messages are generally the main source of memory and disk space growth 
in rabbit, by some margin.

However, other activities such as declaring durable exchanges/queues 
require disk space too. So does writing the log file (which, if it's on 
the same partition as the db dir will eat into the latter's space). 
Rabbit makes no attempt to curtail these activities.

Matthias.
