mongodb - 自动重连 : No replica set members available for query with ReadPreference PRIMARY_PREFERRED

问题 处理此类错误的最佳方法是什么？说后重试，最多 30 秒。 5次？

设置
我在 AWS ECS 上有一个 PRIMARY + 两个 SECONDARY 设置，并且没有一个盒子被关闭。

从异常消息中，Mongo 似乎在说“我没有 PRIMARY，我试图从 SECONDARY 获取数据，但它们也已关闭”。但是，没有一个 Mongo 服务器停机。我有另一个进程正在运行，它有一个默认的 read_preference SECONDARY 并且运行良好。

异常

is_auth = db.authenticate("myid","mypass")
 File "/usr/local/lib/python2.7/dist-packages/pymongo/database.py", line
720, in authenticate
   read_preference=read_pref)["nonce"]

", line 1210, in _send_message_with_response
   raise AutoReconnect(msg, errors)


AutoReconnect: No replica set members available for query with
ReadPreference PRIMARY_PREFERRED

代码

connection = MongoReplicaSetClient(, replicaSet='myReplica-2', use_greenlets = True)
db = "my_real_db"
db.read_preference = ReadPreference.PRIMARY
is_auth = db.authenticate("myid", "mypass") # ERROR at this line

版本
MongoDB:2.2.0 和 PyMongo:2.4.2

最佳答案

检查您的 connectTimeoutMS 和 socketTimeoutMS 。可能是，它很小？
