Behaviour of Couchbase Server once client server goes down

Hi All,
I am new to Integration of Couchbase server with java application on IIB Server.
I want to know what is the Couchbase server behaviour in this situation.
I have open a cluster and bucket and it open the connection with Couchbase server
Now I send a request to fetch the document and at the same time I shutdown the Server.
So what will happen to that connection.I am using Couchbase Java SDK 2.5.2.
So as per my understanding Couchbase server maintain Connection pool.
I want to know whether that connection object will be active in couchbase server or not?
If it will be active then if I repeat the same steps Multiple time then after sometime couchbase server will not able to handle the request.
Please suggest on this.
