LabVIEW quits unexpectedly

[chrys]

I have a pretty complicated VI - with 2 problems.

1. There is one sampling option which when used causes LabVIEW to quit. No warnings, no nothing. Just suddenly disappears from the process list and the screen.

2. When I use a different sampling option the VI samples but then hangs with "LabVIEW.exe has generated errors and needs to close. An error log will be created". The computer then restarts. I can't find the error log anywhere.

Does anyone know what might be creating those errors, or alternatively where the error log can be found? I'm not using anything fancy like ActiveX.

Without knowing more about what your program is doing (or trying to do) it will be pretty hard for anyone to guess what is wrong. If you can post your VI we can take a look at it.

Other things to try:
(1) Run it with the light bulb on and see if you can tell what is failing.
(2) Create your own log file. At various points in the program write to a file the state of the program and of variables you think might be relevant. Be sure to close the file after each write so the crash does not take out the file.
(3) Put a simulation (e.g. random number generator) in place of your sampling option and see if the rest of the program works.
