The problem that the guy who posted this was a hub popping through the material.
If you have a hub shelter, check it to make sure it's not about to happen to you and modify it as I have advised.
Poles break when you aren't opening and closing the shelter properly. Slippery surfaces make the poles go all askew.
Make sure that the wall you are opening/closing is square and not askew (i.e., if the poles look all cockeyed, straighten them out before you pull).
Once you see that it's square (or have made it square) grab it by the corner to steady it and only then pull/push it from the center.
When you get the first section open (usually the roof), let some air get into it before you pull open the next section.
Spray the zippers with WD-40.
I have a first generation QF3. It's one of the first hubs made. Still going strong through good repair and maintenance.
