在推送频率较快时，内存泄露


我在while循环中，每次休眠500毫秒

while (while_flag1) {
  try{
    Thread.sleep(CHANNEL2_SLEEP);               
    }
  catch(Exception e){               
   }
//添加监听器
CometEngine engine = CometContext.getInstance().getEngine();
engine.sendToAll("mychannal","数据2");
}

因为频率较快，所有运行大概几个小时后就报错：内存泄露
