Thank you to all those who joined the stress testing hosts.
We found that it's still possible to break the host by all leaving and rejoining at once.
There's a possibilty that a queue system will cure this completely because the thing that kills the server is just a buffer overrun (running out of space for all the packets) and you see a message "OVERFLOW".
This doesn't happen in normal use because someone would time out long before there is a buffer overflow - so the buffers are big enough. The queue system could solve this by making sure people connect one by one, with a couple of seconds breathing space between each one.
Anyway I'll close this thread as it's misleading now as we aren't really running a stress test right now. It's possible that Patch X release will move to Saturday because we might need to heavily test the fixes tomorrow evening.
Thanks again and good night!
