Get StackOverflow when I specify maxOccurs= "25000"

Hi, faced such problem when I specify at an element maxOccurs= "25000", I receive an error with StackOverflow.

But if I specify maxOccurs= "unbounded", validation passes and I get my xml even in 100,000 elements which is marked maxOccurs="unbounded".
