vi hangs

[LVCoder]

Dear all, I am facing a problem in my VI which sometimes hangs after some time, and i am not able to find out the condition which put it into that hang state. Here is what the VI is doing: 1) In the starting, it writes some information abt the setting to the H/W. 2) Then there are 2 Vi's which are called dynamically. One is for asking H/W settings data, and another is for asking wave data. When the VI starts, it runs the VI which asks for H/W sett data. 3) There is a Stim button(3rd from left in the bottom) on the FP, which when TRUE aborts the Vi and run the VI which calls for Wave data. I dont seem to see any problem with the VI. but sometimes(not always) it hangs. It may hang when i change the Stim Button to True. It may hang when i Click on the Record Button(2nd from left). It may hang when i click the Exit Button. so there is no certain condition on which it will hang. and this is just driving me crazy for the last 2 days and i have banged my head on each and every situation and cudnt figure out the problem. I am attaching my VI here. Pls have a look at it and let me know where the problem is. Ritesh

One more thing .. it doesn't get stuck forever.. it'll remain in that state for arnd 40-50 seconds and gets back to normal state after that.

Could you also attach all the missing subVIs?

I am attaching a RAR file which contains 2 Folders, BERA and Common.

Navigate to BERA->Test->BERA Test.vi.

Hi Ritesch,

there are still some missing vi's.

Your references (Queues and serial) are not valid if you try to close them, because the timeout event sets them to default.

Only the first view, not sure if it solve the problem.

 First thing is that they are not in the shift register, so it doesn't matter if they are reinitialized. And the loop is only closed when the EXIT button is pressed, and in that event i am passing the correct references of the Queues as well as the Serial Port.
