Reply To: ERROR: Unsupported Trxid (101)

You cannot issue a KILL for the reply message, you must issue a KILLREPLY.

When a message is sent with Wait Reply enable, a flag is set to tell the engine to open the IB and take everything in as a Reply messages.  No more messages are sent until that reply is either recieved ofr the Wait Reply time is exceeded and it times out.

The only difference betweena KILL and a KILLREPLY that, in  addition to doing all of  the things a KILL does, the KILLREPLY clears the AWAIT REPLY flag to allow the next OB message to be sent.

Also I noted you set ypu Wait Reply time to 5 seconds.  This is not long enoygh and will probably cause duplicate messages to be sent.  Be sure and set this to several orders of magnitude greater than the longest time it takes the receiver to resond.  As a rule, except for extrodinary circumstances, I set mine to 45 seconds.  It will not affect the normal message flow.  It will only be in affect if the receiver’s port is still active and he does not respond.

It covers those times when perhaps you sent a message and smehow it got lost on his side.
