Labview is crashing (freezing) while running my app.

[BHTC]

Running LV 7.1, the app just freezes while running at random points during execution. How can I purse some help with this?

Thanks,

Bill

Hi Bill,

Could you provide some more information about your application, your system and the crashes?

What are you doing exactly? Acquiring data? Analysis? Data Logging?

What OS are you using?
What are the specs of the PC?
What hardware are you using if any?
What versions of the drivers have you?

Is there any consistency with the crashes? Does it crash at the same point in your code each time? Does it crash after a certain length of time?
Do you get any error messages or does it just freeze up LV?
Is the behaviour specific to this application or have other VIs exhibited similar behaviour?

Sorry if I'm overloading you with questions but the more we know about the problem the more likely it is we'll be able to help.

Hi Sarah,

>What are you doing exactly? Acquiring data? Analysis? Data Logging?
One channel of analog input and serial port communication.

>What OS are you using?

XP Pro with SP2

>What are the specs of the PC?

P4 3 GHz 512 Mb RAM

>What hardware are you using if any?

NI USB-6008

>What versions of the drivers have you?
NI-DAQMX 8.0.1

Crashes at different points. Time to crash is quite variable.

This is the only app I'm running at this point.

It turns out when I run it on a different computer the crash doesn't occur (just tried this). So I assume the diagnosis would be very difficult to make based on the above info.

Thanks,

BTW, that error is from the error log- there is no message displayed when the crash occurs- it just freezes.

Hi Bill,

It does sound like this crash is specific to that machine. I did find a few logs of similar crashes in our notes but there's no record of anyone being able to reproduce the error and hence solve it.

Do you have to use this machine for your application? Could you use the machine you know works?

It is likely that there was a problem with the initial installation of LabVIEW. If you do need to use this machine, I would recommend doing a complete uninstall and reinstall of all NI Software. The directions for this are in the attached word document and the MSI blast software you need is at the following link:

Thank you

We had the same problem today. Did you have success with the reinstallation of LabVIEW?
