I am re-codeing a rpc-xml request that i had written with python in LabVIEW. I have used the python code fairly extensivly with no problem and was able to implement it in LabVIEW. The problem comes when randomly the OPEN TCP CONNECTION seems to hang. Typically I am making about 5 rpc requests/sec. Using TCP dump I have been able to examine the packets and it appears that the final ACK is being sent by the server very promptly, but it appears that it takes 3-4 seconds for the client to move out of the OPEN CONNECTION and into the TCP WRITE.
As a test I moved the code off of the Windows Machine and into a cFP 2120 controller. I was able to run it without problem from the cFP device. The system immediatly responded to the server ACK and sends data without a problem.
I am not sure where to go with this. It seems to be something inside of the OPEN CONNECTION. Does anyone have any insight.
