Memory leak with Power Spectrum function

[Mathilde38]

Hi

I have a memory leak on my application. By observing with the "Desktop Execution Trace Toolkit", the Power Spectrum function (from NI_AALPro.lvlib) seems to have two "Reference leak".

The first one refers to the function "Open VI reference"; I got around this problem by replacing the "Open VI reference" by an "Initialize" input boolean, but I don't understand the second memory leak.

Any idea ?

Thanks...

Hi Mathilde,

Thank you for using NI Discussion Forums!
I reproduce this problem with LV2012 + Desktop Execution Trace Toolkit 2012. I will look further into this.

Are there many calls of this function in your code? Could it be a problem for you?

Thank you.

Hello

Thanks for your reply

Yes there are many calls of this function in our code : about 80 FFT in parallel processes, in an application that runs 24h/24.

So it can be a problem if there is a memory leak.

If you have any idea...

Regards,

Mathilde
