Error messages when using OpenGL ES template

I made a new OpenGL ES application, and without modifying anything, I ran the program. It ru开发者_运维技巧ns, but I see these error messages:

The program displays a colored box that moves up and down. Is this what it's supposed to do? What do these error messages mean?

I've been noticing the same. I'm running iOS sdk 4.1. But it only happens on the simulator.

From what I found at the apple forums, it seems to be a simulator bug. An Apple representative claimed that it was a bug on "their" end.

Here's the quote "This is a bug on our end, but as long as things are otherwise working for you, the logging can safely be ignored."
