Hi 

I am facing with a big problem with rabbitmq, in a pub sub scenario.
In our scenario when a consumer starts it creates a queue, with
rabbitmqctl command I can see the queue with a single consumer but
sometimes we can find queues without a consumer. In the consumer log
there are no errors or warnings about  broken connections with the
server and with netstat command I can see connection ESTABLISHED with
rabbitmq server but in the rabbitmq file I found this error:
=ERROR REPORT==== 8-Sep-2011::14:13:39 ===
exception on TCP connection <0.27709.5838> from ipaddr:port
{inet_error,etimedout}

When this error occurs?
Unfortunately this problem affects 70% of our nodes!

Analysing the rabbitmq log file I found other strange messages:
=WARNING REPORT==== 8-Sep-2011::14:49:08 ===
exception on TCP connection <0.11485.6171> from ipaddr:port
connection_closed_abruptly

This message is repeated a lot of times in the log file, but It seems
that didn't affect the behaviour of our application. 
It's normal to have so much WARNING messages?

And finally these messages:
=INFO REPORT==== 8-Sep-2011::13:13:13 ===
    alarm_handler: {clear,file_descriptor_limit}

=INFO REPORT==== 8-Sep-2011::13:13:13 ===
    alarm_handler: {set,{file_descriptor_limit,[]}}

These are related with socket problems?

All these messages can be related to the same problem, maybe something
with managing connections?
