我正在使用：

celery==3.1.12
kombu==3.0.19
amqp==1.4.5

celery 工这才开腔：

celery worker --without-gossip --without-heartbeat --without-mingle

celery 盘：

CELERY_ALWAYS_EAGER = False
CELERY_EAGER_PROPAGATES_EXCEPTIONS = True
BROKER_URL = 'amqp://guest:guest@127.0.0.1:5672//'
BROKER_CONNECTION_TIMEOUT = 30
CELERY_RESULT_BACKEND = "amqp"
CELERY_TASK_RESULT_EXPIRES = 18000  # 5 hours.
CELERY_RESULT_PERSISTENT = True

有时候我会得到这个错误：

家兔日志：

=WARNING REPORT==== 19-Mar-2016::00:02:17 ===
closing AMQP connection <0.30881.4> (127.0.0.1:26762 -> 127.0.0.1:5672):
connection_closed_abruptly

最大套接字数：

# sysctl -a | grep somax

net.core.somaxconn = 32768

我尝试通过以下方式解决此问题：
1.设置BROKER_HEARTBEAT = 10 -我遇到了更糟糕的情况
1.设置BROKER_POOL_LIMIT =无-相对于当前状态无任何更改
1.将BOKER_CONNECTION_TIMEOUT设置为10、20、30 -超时值越大，错误越少
我认为增加超时值只是隐藏了真正的问题。这个问题的原因是什么？我该如何解决它？谢谢
