IMAQdx out of memory

[_Mike_]

Hi!

I run mid-speed (40fps) image acquisition where each frame I save as binary file. After acqiosition, I run post processing, where each file is to be converted to png file.

When I try to retrieve them, I sometimes run into issue of "not enough memory to perform operation".  What I do is in following snippet:

Could anybody point a problem with this approach? I was sure, that with each for loop cycle I do open and close a file, so there shuld be no memory leak associated with that.
