从芹菜2.4.5升级后，我开始随意关闭芹菜 我在centOS机器上使用celery 3.0.12，boto 2.6和amazon sqs以及django 1.2.7所有这些（底部的pip冻结转储）
我正在运行
service celerybeat start
service celeryd start
我开始吃芹菜后几秒钟就停止了（关机），如果我查看其中一个芹菜原木，我总会看到这个：

我使用maxtaskperchild的低值来快速重新创建关闭。如果我给出更高的值，那么在关闭之前需要更长的时间。
修改
在尝试隔离问题时，我删除了所有定期任务。现在我只有一个周期性的任务和一个基本什么都不做的任务，但我每次都可以重现这个bug。
@task
def myTask():
print 1
return
class test(PeriodicTask):
run_every = datetime.timedelta(seconds=3)
def run(self, **kwargs):
myTask.delay()
print '2'

我想你有一个应用程序，它会以json格式放入你的队列。例如短信。您可以尝试在芹菜设置中更改队列，看看它是如何工作的

将Kombu升级到2.5.4之后的任何版本，因为它是Kombu中的一个错误。它应该在Celery＆gt; = 3.0.20的任何版本中修复（取决于kombu＆gt; = 2.5.5）。
请参阅http://kombu.readthedocs.org/en/latest/changelog.html#version-2-5-5
答案 2 :(得分：0)
就我而言，我使用的是错误版本的python lst5 = data.frame(Data = names(my_data), obs = lengths(my_data))
，但是我需要的是旧版本。
所以我更新了版本：
python3.8
