You could also try running some of the demos from the official Java client to make sure is not a client problem that you have.<br><br><div class="gmail_quote">On Tue, Dec 13, 2011 at 11:42 AM, Simon MacMullen <span dir="ltr"><<a href="mailto:simon@rabbitmq.com">simon@rabbitmq.com</a>></span> wrote:<br>

And when you say that "the server refused attempts to connect", what exactly do you mean. You say that a TCP connection *could* be established - so does your client hang during AMQP handshaking? Disconnect? Something else?<br>

Hello,<br>
<br>
We use RabbitMQ for about a year now. From time to time I upgraded it<br>
and switched from one server to another. About a month ago the last<br>
such transition took place. I installed new RabbitMQ (2.7) on a new<br>
server and our web application was reconfigured. Quite soon we faced<br>
new problems. After some days of stable work clients could not connect<br>
to RabbitMQ. I could list run rabbitmqctl, list queues, kill<br>
connections, but the server refused attempts to connect. That is, TCP<br>
socket was available and telnet could connect to port 5672, but the<br>
AMQP connection could not be established. There was nothing unusual in<br>
the logs. vm_memory_high_watermark is set to 0.7 and there's still<br>
plenty of free memory.<br>
<br>
After a couple of such failures I tried to downgrade to 2.6.1, but the<br>
problem remained. The last time I disabled IPv6, but today we hit the<br>
same trouble again.<br>
<br>
I think I must have done something wrong when setting up the<br>
environment, but what could that be?<br>
<br>
OS: Ubuntu 10.04 LTS.<br>
16GB RAM.<br>
RabbitMQ 2.6.1<br>
Erlang R13B03 (erts-5.7.4) (package erlang-nox from Ubuntu repository)<br>
Client: php-amqplib<br>
