I'm fairly new with mongodb

I have a replica set 3 nodes 1 primary (A) 1 secondary (B) 1 Arbiter (C)

The replica set was created using MMS the 3 node are in 3 different cities

I keep on getting the following error on the secondary that last for lest then a second each time

  1. is it normal

  2. if not any idea how to correct it

           {
                "_id" : 1,
                "name" : "B:27017",
                "health" : 1,
                "state" : 2,
                "stateStr" : "SECONDARY",
                "uptime" : 1213371,
                "optime" : Timestamp(1434051221, 1),
                "optimeDate" : ISODate("2015-06-11T19:33:41Z"),
                "infoMessage" : **"could not find member to sync from"**,
                "configVersion" : 4,
                "self" : true
        },

Thank you

make sure the secondary has at minimum the same priority value as the primary or lower. in my case, i had the secondary priority value higher than the primary's priority

you can check this by running 

mongodcluster:PRIMARY> rs.conf()
