Based on the error messages you see in the logs, I suspect rabbit has 
run out of file descriptors. I recommend the following:

1) check how many network connections rabbit has open, using netstat and 
'rabbitmqctl list_connections'

2) do the same for the producers and consumers, assuming they are 
running under the same user account.

3) if the figures in 1 or 2 look high, check your client code for any 
connection leaks, or rapid opening & closing of connections.

4) Check and possibly adjusting 'ulimit -n' for the user running rabbit.
