Я использую библиотеку pika python для подключения к серверу rabbitmq на локальном хосте.
class BaseRabbitSender(MessageSender):
__metaclass__ = ABCMeta
def __init__(self, host):
self.node = BaseMessagingNode(host)
self.connection = pika.BlockingConnection(pika.ConnectionParameters(
host=host))
self.channel = self.connection.channel()
@abstractmethod
def send_message(self, message):
pass
def close_connection(self):
self.connection.close()
class DirectRabbitSender(BaseRabbitSender):
def __init__(self, host, queue_name):
super(DirectRabbitSender, self).__init__(host)
self.queue_name = queue_name
self.channel.queue_declare(queue=queue_name, durable=True)
def send_message(self, message):
self.channel.basic_publish(exchange='',
routing_key=self.queue_name,
body=message,
properties=pika.BasicProperties(
delivery_mode=2,
))
def close_connection(self):
self.connection.close()
По какой-то причине через некоторое время (например, пару дней) я получаю сообщение об ошибке.

Работает на убунту 13.10. КроликMQ 3.1.3
Я не понимаю, что произошло. Вы можете объяснить?
