Question

我随机收到此错误：IOError: Socket closed。听起来Web请求花费的时间太长（使用Celery任务？）并在响应完成之前终止，因此套接字关闭。但如果我同步调用任务，而不是使用.delay()，我就不会遇到这个问题。

我使用CloudAMQP作为代理，Redis作为结果存储。测试和开发服务器上的一切都完美无缺（开发和生产都使用Heroku）。

CELERY_BROKER_URL = 'amqp://urlhere'
CELERY_RESULT_BACKEND = 'redis://urlhere'
CELERY_ACCEPT_CONTENT = ['json']
CELERY_TASK_SERIALIZER = 'json'
CELERY_RESULT_SERIALIZER = 'json'

芹菜任务：

@celery.task()
def _track(model_type, recipient_id, event_name, properties=None):
    '''Tracks an event for a recipient'''
    properties = properties or {}
    super_properties = _get_super_properties(recipient)
    people_properties = _get_people_properties(recipient)

    all_properties = dict(super_properties)
    all_properties.update(properties)

    member = _get_member(recipient_id)

    try:
        # track
        mp.track(member.id, event_name, all_properties)
    except Exception, e:
        email_body = unicode(e)    
        mailer.notify_dev('Mixpanel error', email_body)
