Client calls Async operations cause server overload

Question

We have a standard WCF service using basisHttpBinding. It is working fine when client proxy call it in sync mode. If client generates service reference by check "Generate asynchronous operations",  client can  consume WCF service in async way (client side). 

I am trying to async send request to server side as fast as possible, I am seeing there server side easily return back "server too busy/ no response" error. 

Is that a way to protect in server side for this case?  

thanks,

I am not using reliable session. It just regular basicHttpBinding with PerCall in service side.
