LabVIEW creates 10000 instances of the recursive VI. This is because LabVIEW does not support concept called tail recursion, see the tail recursion slide of the presentation. If tail recursion was supported, LabVIEW could reuse the same VI instance when making the recursive call, and 10000 iterations would not consume more memory than one 10 iterations. But this is not the case. I really think tail recursion should be supported by LabVIEW but right now it is not and I don’t think NI has any plans to support it in the near future. So use recursion to solve problems that recuire maybe 1000 recursive calls but not much more. At least not until NI implements tail recursion support.

If I change the iteration from 10 to 10000 in the test list.vi, my LabVIEW development system will stop working. Could it be a memory allocating problem?

This is awesome! Thank you very much!!!
