芹菜關機

從芹菜2.4.5升級後，我開始讓芹菜隨機關機。
我使用芹菜3.0.12，博託2.6和Amazon SQS和Django的1.2.7這一切CentOS的機器上（PIP底部凍結轉儲）芹菜關機

我運行

service celerybeat start 
service celeryd start

數秒鐘後我開始芹菜停止（關機），如果我看着芹菜日誌之一，我總是看到這一點：

[2012-12-31 10:13:40,275: INFO/MainProcess] Task patrol.tasks.test[270f1558-bcc2-441b-8961 e1f21a2dbd27] succeeded in 0.318082094193s: None

我用使用低值maxtaskperchild快速重新創建關機。如果我給一個更高的值，那麼關機前需要更長的時間。

編輯

在試圖隔離問題我刪除了所有的週期性任務。現在我只有一項週期性任務和一項基本無所作爲的任務，但我仍然可以每次重現錯誤。

@task 
def myTask(): 
    print 1 
    return 

class test(PeriodicTask): 
    run_every = datetime.timedelta(seconds=3) 
    def run(self, **kwargs): 
      myTask.delay() 
      print '2'

celeryd
