Sorry last stand was that Javier is working on a block to reproduce the 
issue outside our production env but he is ATM bombed with other tasks 
since we entered the final testing phase of the app. The last thing he 
showed me was that in the rampup phase the first request were always 
wrong, but he may be more specific on that.

Due to the patch we applied it is not directly open but I share your 
point we should get to the bottom of the issue.

@Javier can you mockup something we have and state the steps we need to 
reproduce, so Steve may see the problem right away.
