Program Stopped Working Error

[Hoard]

On several occasions, a Labview program that has been running for a long time stops, and Vista gives an error box saying "This program has stopped working".  The Labview program has stopped. Closing and restarting, the program runs fine.  It has run as long as a week without failure; no sign of memeory growth etc.  There does not seem to be any error code or other clue as to what happened.

When running, we have two small programs running concurrently with a larger program, on a computer with two dual core processors (i.e., 4 cores); CPU usage runs under 25% and memory use under 50%.

Hi,

Can you please attach a screenshot of the error?

Sorry for the slow reply; this crash doesn't happen often.  Here is a screen shot when it did so.

Hi Hoard,

As the error is given my Microsoft Windows and not LabView, it can be a system error due to the VI making calls to operating system system files. Can you post the lvlog file for this crash? Thanks!

I have searched the hard drive and can't find a lvlog file... where would it be expected?  The temp directory is

C:\....\AppData\Local\Temp

and the Labview default is

c:\....\National Instruments\LabVIEW 8.5.

Hi John,

The usual location for the log file is C:\Documents and Settings\[username]\My Documents\LabVIEW Data\lvfailurelog\ . See if you can find it there.

The \Labview Data directory contains folders called Dependencies, Downloads, LVAutoSave, and Probes. There are no files in this directory (I have the settings so they would show hidden and system files if they were there). So, there does not seem to be such a file.

Hi John,

At this stage, without a log file or at least some steps to reproduce, we cannot point out the cause of your issue. Keep us updated if anything else happens and call National Instruments if you face this issue repeatedly.
