這似乎解決了一個非常類似的問題，但並沒有給我足夠的洞察力：https://github.com/celery/billiard/issues/101聽起來像嘗試非SQLite數據庫可能是一個好主意...Django 1.6 + RabbitMQ 3.2.3 + Celery 3.1.9 - 爲什麼我的芹菜工人死亡：WorkerLostError：工人過早退出：信號11（SIGSEGV）
我有一個簡單的芹菜設置與我的Django應用程序。在我settings.py文件我設置爲運行如下任務：
CELERYBEAT_SCHEDULE = {
'sync_database': {
'task': 'apps.data.tasks.celery_sync_database',
'schedule': timedelta(minutes=5)
}
}
我按照這裏的說明：http://celery.readthedocs.org/en/latest/django/first-steps-with-django.html
我能夠打開兩個新的終端窗口，並運行芹菜流程如下：
ONE - 這是需要計劃任務，並把任務隊列中的芹菜拍過程：
PROMPT> celery -A myproj beat
celery beat v3.1.9 (Cipater) is starting.
__ - ... __ - _
Configuration ->
. broker -> amqp://[email protected]:5672//
. loader -> celery.loaders.app.AppLoader
. scheduler -> djcelery.schedulers.DatabaseScheduler
. logfile -> [stderr]@%INFO
. maxinterval -> now (0s)
[2014-02-20 16:15:20,085: INFO/MainProcess] beat: Starting...

[2014-02-20 16:20:20,161: INFO/MainProcess] Writing entries...
TW Ø - 芹菜工人，這應該接受這個任務從隊列中並運行它：
PROMPT> celery -A myproj worker -l info

當任務被髮送，然而，似乎時間大約50％的工人運行任務和其他50％的時間我得到以下錯誤：
[2014-02-20 16:35:20,159: INFO/MainProcess] Received task: apps.data.tasks.celery_sync_database[960bcb6c-d6a5-4e32-8267-cfbe2b411b25]

我正在開發運行小牛的Macbook Pro。
芹菜版本3.1.9 的RabbitMQ 3.2.3 的Django 1.6
請注意，我用的Django的芹菜3.1.9並啓用了djcelery應用。
