RP doesn't bind itself to a TCP port, it uses IPC/Remoting so it must be something else. You might try some minimal set of services and progressively start the other services one by one until the error appears. But as the error seems to be random, that hunting would be very boring thou. I think it's. Even if users start to post junk there, I can close them and pay attention to the ones that matter. I can post issues I find myself to keep things organized as well too. Also, BitBucket sends an email for every issue posted there, here at Guru3d I receive only one email for the post right after my last visit, if I take a day to visit the forum again, the thread might have dozen of new posts to read and reply. But let's see how it works. If it starts to give me more work than benefits, I'll close the issue tracking.
