Waveform Generation blocks go out of memory

[biomed87]

Hi,

I have a simple program in which I generate a pink noise thanks to the Inverse f Noise Waveform block and then I send it to the soundcard. I have to do sound tests in which this VI plays the noise for many continuative hours, but after a few hours LabVIEW stops and says that is out of memory. When I close the pop-up LabVIEW indicates that the problem comes from the Inverse f Noise Waveform. If I monitor the VI process while it is running, I can see that the private bytes of the virtual memory slowly increase up to full a few gigaByte, then the VI stops.

Which is the problem?

Note: this out-of-memory problem arises even if I use different blocks (as white noise or sine waveform) in place of the pink noise one, so I think it's related to Waveform Generations blocks in general

Hi biomed87,

have you tried setting the reset signal wire to true? Also, can you attach your code so we can see if there is something in your code that is not optimal and is causing that error? Thanks,
