Some more data points: v6 patch, with my laptop plugged directly into the gigabit ethernet switch which is connected to the web server: - Worked perfectly 5 times in a row. v6 patch, with my laptop next to the wifi aerial: - Bug is harder to reproduce, maybe only happens 50% of runs. v6 patch, with my laptop about 100' from the wifi aerial: - Bug reproduces on every run. So something to do with long latency links. Question: Is there a place in the patch we could put a sleep in order to simulate a long latency link? I also checked the logs on the web server. There are no errors, and each access returned a 200 or 206. So the problem doesn't appear to be at the web server end.
