Question

为了解决与打开的大量数据库连接相关的问题（OperationalError（＆＃39;致命：为非复制超级用户连接保留剩余的连接插槽\ n＆＃39;，））我试过使用https://github.com/jneight/django-db-geventpool并更新了DATABASE设置，但它没有与芹菜一起使用，所有队列都被卡住了。

我不知道它是否与本节https://github.com/jneight/django-db-geventpool#using-django-16-orm-when-not-serving-requests相关，但我不知道如何应用它。

我正在使用：

 - Django 1.9.2
 - celery 3.1.19
 - gevent 1.1b1

我有以下芹菜文件：

# -*- coding: utf-8 -*-
""" Celery configuration file
"""
from __future__ import unicode_literals
from __future__ import absolute_import

import os


def post_fork():
    """ post_fork
    # if its a gevent queue (all queues except scrapy-* queues)
    """
    from gevent import monkey
    monkey.patch_all()
    from psycogreen.gevent import patch_psycopg
    patch_psycopg()


# post_fork must run before anyother imports
if os.environ.get('GEVENT', None):
    post_fork()

from celery import Celery
from django.conf import settings

from etc.celerybase.routers import GlobalRouter

os.environ.setdefault('DJANGO_SETTINGS_MODULE', 'settings.sites.app')

app = Celery('pb', broker=getattr(settings, 'BROKER_URL', 'redis://'))

app.config_from_object('django.conf:settings')

# Optional configuration, see the application user guide.
app.conf.update(
    CELERY_TASK_SERIALIZER='json',
    CELERY_ACCEPT_CONTENT=['json'],
    CELERY_RESULT_SERIALIZER='json',
    CELERY_DEFAULT_QUEUE='low',
    CELERY_DEFAULT_EXCHANGE='low',
    CELERY_DEFAULT_ROUTING_KEY='low',
    CELERY_CREATE_MISSING_QUEUES=True,
    CELERY_ROUTES=(
        GlobalRouter(),
    ),
)
