Two waytwo-way communication on labview using the TCP / IP

I recently made ​​a small project for my final project. System specifications are as follows:
There are two computers, for example, computer A and B. Each computer perform data acquisition temperature. then send the data to another computer acquisition. Computer A to Computer B, and B to A. And I must do it with LabVIEW.

last week I have been trying to do a two-way communication using the TCP / IP (I include the file). There are two applications that make communication VI client and server, where the application server to hear if there is request data from the client, the application server will send data to the client. successfully transmitted data is a two-way data string.

Meanwhile, for the acquisition of data, I was able to do it for each computer (I include the file too). For data acquisition by chance I menggukan arduino.

the problem is, when I combine the two-way communication between computer A and B, which sends the results of each data acquisition computer. In a few seconds there is a message: "Buffer Overflow";

I am very confusion to make a reliable two-way communication ...
I stalled for weeks for this ..

I would be very grateful for all the replies ..
