DNPR issue while setting the redundancy

One thing you can check/try is setting the ExclusiveAccess parameter (I think that is what its called) per each device (primary and secondary). We have experienced issues with field devices that will only accept one DNP TCP connection at a time, so when the other server checks its connection it will break the connection with the first server.
