RabbitMQ保持关闭连接

Question

I'm using rabbitpy python library to interact with RabbitMQ. I designed a communication class that have a publisher method and a consumer method. This communication class' instances run in separate threads.

If I begin frequent requests, RabbitMQ closes connection. Here is the error log:

=ERROR REPORT==== 4-Apr-2014::14:12:52 ===
AMQP connection <0.13197.22> (running), channel 1 - error:
{amqp_error,unexpected_frame,
            "expected content header for class 60, got non content header frame instead",
            'basic.publish'}

=INFO REPORT==== 4-Apr-2014::14:12:52 ===
closing AMQP connection <0.13197.22> (127.0.0.1:52234 -> 127.0.0.1:5672)

=INFO REPORT==== 4-Apr-2014::14:12:52 ===
accepting AMQP connection <0.13263.22> (127.0.0.1:52237 -> 127.0.0.1:5672)

rabbitpy is a thread safe library (it says so).

Why am I having such a problem?

Answer 1

Looks like problem is multi threading. May be it's a bug in rabbitpy . The solution is to either

• Avoid publishing on the same channel within connection from multiple threads
• Synchronize publishing in your own code
