{{Quickfixn}} QuickFix.MessageParseError - FIX 4.4

[Rao, Masthan]

Hi,
            I am getting the following error in "OnOutgoing" and "OnIncoming" methods while parsing FIX messages. The same code is working FIX 5.0 specification but when I am using the same code for FIX 4.4 for another client its throwing the following error. While debugging when I hit the OnOutGoing method first time the method session.GetMessage is succesffuly parsing the message "8=FIX.4.49=10135=034=249=ABMKTDATAUAT52=20160506-07:55:49.41856=xxxxxxx553=xxxxxxx554=wu7fy3kih9iL10=131".
Immediately  again I am hitting OnOutgoing message and this time I am getting message "OUT: \n 8\t(BeginString)=\t\tFIXT.1.1|\r\n9\t(BodyLength)=\t\t126|\r\n35\t(MsgType)=\t\tA|\r\n34\t(MsgSeqNum)=\t\t1|\r\n49\t(SenderCompID)=\t\xxxxx|\r\n52\t(SendingTime)=\t\t20160506-05:23:45.993|\r\n56\t(TargetCompID)=\t\xxxxxx|\r\n553\t(Username)=\t\xxxxxxxx|\r\n554\t(Password)=\t\xxxxxxxx|\r\n98\t(EncryptMethod)=\t\t0|\r\n108\t(HeartBtInt)=\t\t30|\r\n141\t(ResetSeqNumFlag)=\t\tY|\r\n1137\t(DefaultApplVerID)=\t\t9|\r\n10\t(CheckSum)=\t\t110|\r\n -(UNKNOWN Tag)=|\r\n"

Which the FIX engine is failing to parse and throwing error. Not sure where I am going wrong. Can you guys please help?

Sample code
        public void OnOutgoing(string msg)
        {
            try
            {
                Session session = Session.LookupSession(ActiveSessionID);
                ABFixMessage message = new ABFixMessage() { Message = session.GetMessage(msg) };
                Log(message.Message, msg, "OutGoing");

                if (outgoingMessageBufferBlock != null && !msg.StartsWith("OUT:") && ActiveSessionID != null)
                {
                    if (message.Message.Header.IsSetField(56) && message.Message.Header.IsSetField(49))
                        message.Source = isAcceptor ? message.Message.Header.GetField(56) : message.Message.Header.GetField(49);
                    outgoingMessageBufferBlock.Post(message);
                }
            }
            catch(Exception ex)
            {
                logger.Error("OnOutgoing", ex);
            }
        }
