这是一部分日志，好像在Linux上不怎么容易挂掉 ，在windows平台上多操作几下就死了

Answer 1

我发现用debug 和RUN 模式运行部署的项目 debug很快会死， RUN好像就不怎么会死呢？

Answer 2

我在类里用了Vector 返回对象数组，但好像说需要关闭， Vector =null; 我不知要在哪里关闭；是在该方法的类里还是在引用改方法处关闭？
public Vector listInfor(int strpage ,int pagesize){
 PersistentMgr linkdb = null;
    ResultSet rs = null;
   
    try {           PersistentMgrFactory factory = new PersistentMgrFactory();
          linkdb = factory.newPersistentMgr();
          SQL="select * from infor order by I_top desc limit "+ (strpage-1)*pagesize+","+ pagesize;
          linkdb.prepareStatement(SQL);
       rs=linkdb.executeQuery();
       Vector vector = new Vector();
       Infor infor=null;
       while(rs.next()){
     infor=new Infor();
     infor.setI_id(rs.getInt("i_id"));
     infor.setI_name(rs.getString("i_name"));
     infor.setI_source(rs.getString("i_source"));
     infor.setI_time(rs.getString("i_time"));
     infor.setI_image(rs.getString("I_image"));
     infor.setI_top(rs.getString("i_top"));
     infor.setI_author(rs.getString("i_author"));
     infor.setIt_id(rs.getInt("it_id"));
     infor.setI_content(rs.getString("i_content"));
     vector.addElement(infor);
    }
       linkdb.close();
           linkdb = null;  
        return vector; 
      
    }catch (Exception ex) {
      System.err.println("执行"+CLASS_NAME+".listBlogtype语句出错: " + ex.getMessage());
      return null;
    }
    finally {
      try {
       if (rs != null) {
              rs.close();
              rs = null;
            }
       
        if (linkdb != null) {
          linkdb.close();
          linkdb = null;
        }
      }
      catch (Exception ex) {
        System.err.println("执行"+CLASS_NAME+"listBlogtype.closeDB语句出错: " + ex.getMessage());
        return null;
      }
    }
}
