Unstable
Great app, but it keeps crashing. It stops responding, but resumes operation after restart. Not sure what causes it, but maybe invalid query params, or several simultaneous queries. I have tested it on OS X with Node v0.10.35 and on Linux with Node v0.10.26.
I think I need more information about what query parameters you've passed to the server and the amount of your system memory. I saw the case that it only worked once then it starts to become unresponsive. That system has 128MB of memory and the server just used it all. On memory-constrainted system this is likely to happen.
Do you know how the memory usage depends on the number of simultaneous users/streams?
