The problem is your server is running a bunch of services as you have detailed such as web services. All of these services can easily add up to attack each and every service and cause stress towards the server and of course you yourself still need to do some basic measures to prevent attacks.

I would also recommend as suggested here monitoring your traffic and packets during a attack and see if it is actually your game server being attacked.
