I'm having trouble with a production query that is exhibiting strange behavior. The first time or 2 that it is parsed following an instance start, it chooses a bad plan. Shortly thereafter it will start choosing a different (better) plan. What factors could cause this behavior? The stats have not changed, nor have the system stats. I have 10053 traces for both the good and bad plans. Is this an ok forum to ask such a question? I've had an SR open for more than 2 months with no valuable suggestions to show for it.

This is what we need it. In an age where MISinformation can cause a lot confusion/frustrations. It's refreshing, to get information right from the source.
