LabVIEW
TCP/IP PROGRAM ERROR
Hello Alan,
your keyboard is broken, check the shift and caps-lock button. Somehow your header, first and last line are in caps. The rest of the messge lacks any upercasing, weird...
On topic, your server VI is a bad program. It has a memory lake functionality.
The inner loop will never finish in a normal way, only when the memory is full and the program is aborted. (like you experience).
By using a timeout of 0 ms, the Time-out output will always be True, and the loop will continue to run. What's the purpose of this?
Your upper inner while loop (that feeds the queue), will not end until the lower while loop has finished and the queue is killed, what's the purpose of this?
You should have been able to detect these issues by taking debugging steps instead of running of to these forums?
Use the supplied tools (execution highlighting to start with) to track such things!
Good luck,
Ton
LabVIEW user groep First try to run your server VI with execution highlighting ON.
And you need to establish what you want to do!
What do you want to serve via the TCP/IP connection?

If you want to sent the file via tcpip, there are several functions in your current program you don't need.:
-Convert the file to an 2d-array of strings, I would do that on the client side
-transport the file inside your server VI via a queue
-expand the 2d-array over and over until your VI crashes.
If you run your VI in execution highlighting mode, you'll see that the read-queue loop, NEVER FINISHES and that the array is growing with every iteration, making your VI crash.
Please post your progress!
