我使用Curator客户端来操作zookeeper服务器，但是如果我同时启动十个线程来操作zookeeper服务器，总是失败。
如果线程数小于6，它工作正常，当连接丢失时，我必须重新启动zookeeper服务器。有人知道如何解决这个问题吗？

curatorClient = CuratorFrameworkFactory.builder().connectString(zkAddress).sessionTimeoutMs(Constant.ZK_SESSION_TIMEOUT).connectionTimeoutMs(Constant.ZK_CONNECTION_TIMEOUT).retryPolicy(retryPolicy).build();
curatorClient.start();

我做了以下操作：创建一个新的回调函数。（）. callback（）. callback（）. callback（）. callback（）. callback（）. callback（）. callback（）. callback（）.锁获取（）;..
错误：

然后我添加ConnectionStateListener和UnhandledErrorListener，我得到了以下信息：

newState.isConnected()false
 SUSPENDED
 newState.isConnected()true
 RECONNECTED
 newState.isConnected()lost
 RECONNECTED

  unhandledErrorListener:Background operation retry gave up
  Background retry gave up
