Hello, not sure if a thread exists, but our rFactor2 Server 32bits (not tested in 64bits) is constantly growing in memory usage without doing nothing. The server has no plugin installed, and it's parametrized to run the session Practice/Qualif/Warmup without any player (so change session by session at the end of them). It growing around 100 MB by day.
also see this thread: http://isiforums.net/f/showthread.php/20772-Server-memory-usage-Build-770-64bit There are a few people who are experiencing this.
I don't think so, On my B798 32bit server, my memory for each server is growing. Not as important than b770, but growing. Not tested on 64bit version.
