No, I can not confirm it. You posted a trivial script that did not show me any bug or tell anything about that problem. Why must such an issue always cause discussions? You have a problem, you report it, I suggest that you contact the support - that's it. They can do a lot more than I, like checking your logs or your historical data or whatever might cause the problem. They will find it. If you do it or not is of course completely up to you.
