labview stops working over night

[Scherni]

Hi,

I have a big problem with my labview program.

The program should work over night to record data. The Problem is it stops working in the night.

It always happens at different times and in different positions of the program.

I already tried both, to lock the comuper over night (would be better) and to keep it unlocked.

The energy settings are turned off and the computer is not connected to any network.

I am out of ideas what the reason could be.

I am happy about any suggestions

Yours Scherni

It could be a memory issue. Do you get an error when it stops? Are you collecting any data and are you using arrays? It could be that you run out of memory. 

[Scherni]

I don't get any errors....that's my big problem. So I don't know what the reason is for the stop.

What I forgot to say is that when I click on the labview program (or unlock the computer) the program continues working.

I use some array, but not for data acquisition. In the arrays there are only some data stored.

You should post some code.

I've never seen a program simply "standing by" on its own. So either there are some segments of code blocking execution or you have a really, really odd "feature".

Also you should give some figures on your system like:

OS?

LV version?

Did you log system parameters using Windows Performance Monitor?

...

thanks,

Thanks,

I attached the main vi. If you need the SUBVI's too, please let me know.

The code is programmed with labview 2011.

At the moment it is running on an 30 day evaluation version of LV2012. When I'm done programming I will create an EXE or an installer.

OS is Windows XP, CPU=Pentium 4 (2,8GHz), RAM=4GB

I didn't log system parameters using Windows Performance Monitor.

But I will try doing this tonight.

For German readers: there's some more information already known...

[Scherni]

Sry..only 1GB of RAM is in the PC.

[EvenDeejay]

That leaves you 500-600 MB left.. Which could be an issue if your software is not optimal.

[Scherni]

It is running at the moment and the tast manager tells me that 600MB are in use at the moment.

So it seems to me as if there is enough free space?!?

[EvenDeejay]

well, you got almost 400MB left. If you run your program, do you see any increasing memory useage?
