To get a better idea of what is causing this, open your call stack window in VS (Debug --> Windows --> Call Stack) and that should give you an idea of what is causing it. I assume you know what an infinte loop is and recursion can also be likend to an infite loop if implemented incorrectly, consider:

Private Sub foo()
   Dim i as Integer = 0
   While i = 0
   End While
End Sub

So recursion is the technique whereby a Method or Function calls itself until some condition is met but, as the example above shows, there is no condition to stop the recursion since i is never incremented the While loop will continue to call the method foo()

You can also get a recursion loop if your code is firing off multiple events. For example. You might handle a textchanged event on a textbox control and then modify the text accordingly, like change to uppercase for user input, but this triggers off the textchanged event again, and so on.
