This is the wireshark log of the traffic on one of the machines in the case that does not work: http://rpi.edu/~doriad/cloud3_cloud3+6.wsk I see a bunch of red lines, where in any of the working tests cases I do not see any red lines. As you can tell from my analysis, I am an expert wireshark user (haha!) - can anyone interpret the problem from this file? Maybe I need to ask the wireshark mailing list for an analysis?
