Hi Vedanth,

Can you execute the command `rabbitmqctl report` against your broker and 
post the output please? Are you by any chance running rabbitmq in an 
environment with a limited amount of memory? This situation can occur 
when the mounted file system rabbit is running on has very little 
memory: the broker starts and almost immediately the disk alarm goes 
off, which prevents you from using rabbit (as producers become blocked 
until we've managed to reclaim enough disk space to handle throughput
