Labview 7 Express performs Illegal Operation

[plp122]

Hi,

I have a Labview application to control a small diesel engine. The program runs and controls everything in the right way, but after about 5 hours of operation the program crashes and shuts down. As the program also controlls the throttle and dynamometer in the engine system, everything is shut down once the programs crashes. The error message that I get is in the attachment. Thank you very much for your help on this issue. Peter Perez

Hi.

The information you provided isn't meaningful if you don’t give us a context description. By context i mean:

  * LabVIEW version
  * some insights about the VIs you are using (diagrams?)
  * some more information about the specific offending VI (


cheers,

Peter,
       This sounds like a memory access violation error.  A page fault is generated when errors occur while moving pages in between your system memory and virtual memory.  What all is in your code?  Are you doing anything with ActiveX?  Is the application an executable?  What hardware are you using?  Have you tried running this application on another computer?  What other software do you have on your system?  Is this a very large application?  What are the specs of your system?  How much virtual memory have you allocated?

Just a few guiding questions that might help determine were this page fault is generated.

Thanks,

Nathan
