We have been running a single instance of Mongo for a number of years now with our application without any issues at all.
We have now set up a replica set with 3 members: 1 primary, 1 secondary and an arbiter.
After a couple of hours our application simply stops working with the database i.e. it hangs. Below is an extract from the database log file from the primary server. In this log the activity seems to stop at 14:09:15 with our application (running on 192.168.45.105). Address 192.168.45.106 is the secondary server. All we get after that is successful authentication and nothing else. If we restart our application it stops on the first database call. If Mongo is restarted on the primary and secondary servers and then our application restarted it works again for another couple of hours and the cycle repeats.
