Question

我有一个芹菜与两个工人一起跑，看着他们我看到他们分别接受4个任务，处理它们，然后停止处理任务。（请注意，这些任务是长时间运行的，最多可处理2分钟。）

celeryctl提供以下信息：

django@server: ./manage.py celeryctl inspect active
<- active

    * celery.backend_cleanup

celery_haystack.tasks.CeleryHaystackSignalHandler
    *
celery_haystack.tasks.CeleryHaystackUpdateIndex
    * convert.tasks.create_pdf
    * convert.tasks.create_pngs

此外，每次发生这种情况时，要打印到日志的最后一件事是：

[2012-06-01 12:17:53,777: INFO/MainProcess] Task convert.tasks.create_pdf[319984de-5bc4-47fc-891f-273d827d625f] retry: None
None
[2012-06-01 12:17:54,327: INFO/MainProcess] Task convert.tasks.create_pdf[8a89f3c1-e991-487e-a2db-a57d23bae17f] retry: None
None

这些任务也恰好在打印之前就已经失败了，在我的代码中我所谓的是：

except HTTPError, e:
    statsd.incr('A.stat')
    log.warn('Woops: %s', e)
    create_pdf.retry()

如果我杀了celeryd（^ C，它会立刻死掉，没有等待任务）并再次启动它继续，就像没有任何事情发生再做一些任务而再次死亡（我认为它始终在{{1任务，但日志显示此任务失败并正在重试而没有问题）

这是芹菜的一个已知错误，已在v3.0中修复。（Issue 707）

芹菜工人停止处理任务
