I'm using Zookeeper - so no static lists at all. It's not really reproducable because it occurs only after a couple of hundred messages have been sent. But it usually occurs within the first 1000. I tried it with github/trunk as well as with 0.6.
I literally copied the code from the simple producer / consumer example.
