<p class="MsoNormal">Hi, <o:p></o:p></p>
<p class="MsoNormal"> <o:p></o:p></p>
<p class="MsoNormal">I need help on an issue in BigIP/F5 load balanced rabbitMQ cluster. We set up a cluster of two RabbitMQ servers which were fronted by a BigIP load balancer.<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">When running a client program (Java based) to send messages to each rabbitMQ server directly, it works fine. However, when using the same client to send messages via BigIP VIP (pointing to the RabbitMQ cluster), I got the following error.
Double checked the BigIP setup, and it seems right (TCP/IP timeout set at 5mins). Thanks for shedding some light on it.<o:p></o:p></p>
