Some FIX Engine vendors implement socket connections for the application comms that use a "send request / get positive ack" model rather than implementing sequence numbers. If this is the case, then you will need to establish a timeout period after which you will decide there is trouble with your socket communication or FIX engine. Typical responses to Application/FIX Engine TCP comms timeout include 1. Disconnecting and reconnecting the socket to the FIX engine, and, 2. If this succeeds, send the message again (if desirable) with a PossResend flag set (cannot set PossDupe since we can't establish the MsgSeqNum). Other approaches make sense too and depend on the nature of the message traffic. For example, if sending order traffic, you may want to: 1. Mark the FIX session as down in your application, 2. Try to re-establish FIX Engine connectivity, and 3. Send an OrderStatusRequest to determine if the order made it to the market rather than auto-resending it a bit late. 4. Mark FIX session as up and update order status depending on the response to the OrderStatus request.
