This is probably an "ordinary" memory leak, but just in case: Is it somehow possible to disable the built-in HTTP server just to see if it makes any difference? Just curious if someone (not rFactor2) attempts to probe it. You would be amazed how quickly port scanning attempts find services like a HTTP server, even when running on nonstandard ports, and try to figure out what operations it supports...
There is no way to turn it off but blocking the ports would rule out your theory.
