If I poll the same addresses using some other Modbus Master Simulator it is working fine..!!

Yes, I noticed in wireshark that some TCP Retransmissions have happened and few DupAck’s also. After that the polling pattern has changed, It used to poll at addresses 110,124,138,163,13C before TCP Retransmissions but after that it is polling at same address for twice or thrice continuously and at other addresses it is polling once. Why this would have happened? If I close the connection and re-establish then it’s working fine until some TCP Retransmissions occur.
