Are you sure that the channels are still open?

Can you be more specific than "does not work"?

If you get a channel exception, the channel is closed and can no longer
be used. Inspecting RabbitMQ log will make it easy to notice.

Another thing that may be happening is RabbitMQ throttling your connection.
It can be easily seen in the management UI and should not affect
channels that only consume messages.

I assume AMQP_RESPONSE_SERVER_EXCEPTION indicates
a channel exception. You need to investigate what exactly causes
it (see the log) or use a new channel.
