如何解决beam.smp的内存使用情况？

Question

我正在使用芹菜和Rabbitmq进行后台作业。在运行程序时，我的内存消耗正在增加。一段时间后，将显示此错误

[2014-08-06 05:17:21,036: ERROR/MainProcess] consumer: Cannot connect to amqp://guest:**@127.0.0.1:5672//: [Errno 111] Connection refused.
Trying again in 6.00 seconds...

所以我尝试按照以下命令重置Rabbitmq

sudo rabbitmqctl stop_app
sudo rabbitmqctl reset
sudo rabbitmqctl start_app

的输出

rabbitmqctl list_queues

显示了很多队列，如下所示（我已经显示了一些）

我尝试过以下设置是芹菜配置文件

app.conf.update(

    task_ignore_result=True,
    task_store_errors_even_if_ignored = False,
    worker_enable_remote_control=False,
    accept_content = ['json'],
    task_serializer = 'json',
    result_serializer = 'json',
    result_persistent=False,
    result_expires=60
)

仍然，我面临着同样的问题。
