builder.setSocketOption(StandardSocketOption.SO_SNDBUF, 16 * 1024);
builder.setConnectionPoolSize(1);
builder.setCommandFactory(new KestrelCommandFactory());

心跳检测失败，你连接的是memcached吗？需要支持version协议。

我使用的是cmem，怎样才能避免这个问题。

memcachedClient.setEnableHeartBeat(false);

我已设置此参数但还有这个问题。请看我配置

是个bug，发现某次提交将这个参数失效了

感谢。暂时你可能需要回滚到1.3.7或之间的版本。或者可以bui
ld github里的最新源码，我刚fix了。

回滚到1.3.7之前版本，心跳包问题没有，但出现超时，配置同
上，是否是配置问题

（1）CMEM是分布式系统，不能支持异步客户端，例如Spymemcached
。
也就是说同一个连接上连续发送请求A、B、C后，其回复顺序��
�不确定的，任何基于顺序的逻辑都不能正常使用，因此必须�
��用一问一答的同步模式开源客户端。
（2）CMEM的socket连接有超时限制。如果从上一次访问后的180秒
内，客户端没有访问请求，则连接会自动断开。因此客户端��
�180秒内至少要发送一次访问请求。
（3）到一台CMEM的socket连接数是有上限的，但此上限远大于客
户端能够创建的临时端口数，因此使用时无需关注。

CMEM有限制，xmemached也是异步client，也用不了，CMEM的性能看起
来也不怎么样，没有特别必要似乎也不需要用它。
