After finally entered a server and run Ember 0.5.3 for some time I saw that memory usage was rising constantly. After 20 mins the increase was about 4k/second. This was constant even if I left the game alone.
Hi, this is something I've seen before, but thought had gone away. I've added a bug report https://bugs.launchpad.net/ember/+bug/273878 and will look into it. Thanks for your report.
