Spymemcached掛起操作完成後

我正在使用Spymemcached訪問服務器上的Memcached。我開始使用以下命令Spymemcached掛起操作完成後

memcached -m 4096 -p 11211 -u memcache -l 127.0.0.1 -d -vvv

Memcached和我使用下面的驅動程序把一些鍵/值對的內存緩存。由於某種原因，在最後的get操作之後，main函數只是掛起;它永遠不會終止。

import java.net.InetSocketAddress; 
import net.spy.memcached.MemcachedClient; 

public class memcache { 
     public static void main(String args[]) { 
       //Connect to Memcache. 
       MemcachedClient c=null; 
       try{ 
         c = new MemcachedClient(
           new InetSocketAddress("127.0.0.1", 11211)); 
       } catch (Exception e) { 
         System.err.println("Could not connect to Memcached."); 
         System.exit(-1); 
       } 
       System.out.println("Connected to Memcached."); 
       Object myObject = null; 
       for (int i = 0; i < 10; i++) 
       { 
         c.set(new String("HELLO"), 3600, i+1); 
         myObject=c.get("HELLO"); 
         String value = myObject.toString(); 
         System.out.println("***" + value); 
       } 
       System.out.println("Done."); 
       return; 
     } 
}

我得到以下輸出，但應用程序永遠不會終止。

什麼問題，則可能會導致main功能永遠不會終止？有沒有人有什麼建議？

解決方案很簡單。當它完成客戶端必須斷開：

c.shutdown(...)

的例子包括沒有這一關鍵的一步。
