It's not the disk space but I'm not sure of how to answer this question.
Looking at the rabbitmq at curtiz.log.1, the last event reported is a tcp
connection attempt but no trace of the fulfilling of it.
Looking at rabbitmq-sasl.log.1 I just have this message :
=SUPERVISOR REPORT==== 23-Nov-2011::17:36:29 ===
     Supervisor: {<0.1220.149>,
                                           rabbit_channel_sup_sup}
     Context:    shutdown_error
     Reason:     shutdown
     Offender:   [{pid,<0.1222.149>},
                  {name,channel_sup},
                  {mfa,{rabbit_channel_sup,start_link,[]}},
                  {restart_type,temporary},
                  {shutdown,infinity},
                  {child_type,supervisor}]


I've limited the amount of memory to 20% and i'm using blocking connection
with pika to publish a message. Here is the python code :
    connection =
pika.BlockingConnection(pika.ConnectionParameters(host=host))
    channel = connection.channel()

    channel.queue_declare(queue=queue, durable=True)

    channel.basic_publish(exchange='', routing_key=queue, body=url,
properties=pika.BasicProperties(delivery_mode = 2,))

    connection.close()

I have remarked that i have a lot's of connection running at the same time.
Could it be a too high amount of connection to the server that crashed it ?
Do you think i don't close properly the connection knowing that there is 6
instances of my program running at the same time ?

I managed to restart the server so it solved the problem. Thank you.
