Hi BR,
I don't known how to reproduce, not yet :-)
I couldn't identify which worker was responding too, but I can see with
strace warnings in the old wolker about EAGAIN (Resource temporarily
unavailable). I can see that because old workers still running:

Looking for our user's usage, this workers will stay online for more few
hours :)
The difference between old and new configuration is just a "down" flag in
one of our servers from our websockets pool (upstream). You can see a
simplified version of config on: http://pastebin.com/02GQQ22r
Really thanks for your attention.
Igor
