why does my lab/windows debuggable executabe program just quit?

[ronbo]

I have a lab/windows cvi program which runs multiple instruments(8).  Lately, with no indications of failure, it just quits.   This program  runs autonomously 24/7.  The only interruption is at slightly before midnight it is turned off by a script command and then at just after midnight the computer is turned off and then on again.  The executable is in the start-up menu so it starts up.  Just fine.  Then sometimes, not every day and at no certain time it program just quits.  Has anyone else experienced a similar problem?

I had something similar once.  Have you tried increasing the Maximum Stack Size in the Build Options window under the Options menu?

You might try looking into the event logs if you're running on Windows, to see if the system logged a reason for the program termination.   The event viewer is accessible from the control panel / administrative tools submenu.
