Can't close a Task

[eldar]

I have written an application with Visual Basic .net, I use 2 tasks simultaneously, the first one is for capturing data with the class AnalogUnscaledReader and the second task is to write this data using the class AnalogUnscaledWriter. The system is working correctly, but when I try to stop the output task then the application crash. I can stop the input task but not the output task.
What could be happening?
Analog Output (NI PCI-6723)
Analog Input (PCI-6071E)

If you could attach the application, I could run it and test it.
