Re: 100% CPU usage and double timeout bug

I am not at all a Labview programmer, but we had a similar issue of CPU pegged and weird things happening, and it turned out to be certain "tasks" (events? what do you call them?) being executed in pseudo-random order in the loop because they were not wired together, like I suppose they needed to be, but nowhere documented that they had to be. I believe one of the things that was part of the issue was the way we had implemented the compressor code or library.

Sorry for the vague description. That's the best I have from my student. He knows what he's doing but can't communicate it to a level I can understand and re-communicate. This is why I'm the design and mechanical guy. :/
