These are the only leaks i have after some heavy usage:

The only responsible thing here is UIScrollView – which may come from any table in my app.
I have only one custom UIScrollView. Here is the only thing I do with my scroll view:
self.scrollView.contentSize = CGSizeMake(320.0, 40+height);
I also have one UIWebView, which also have a UIScrollView.
Should I worry about those leaks? As you can see they go up to 4KB, and with more time of usage, they may use up even more!
Thank you!
It’s a known bug in 5.1 and 5.1.1 and will be fixed in a future release.
I’m not sure I can quote anything from the Apple developer forums, but if you have a developer account, you can find more info here.
