   你配置的参数太特殊了， 刚好 client idle timeout = server idle timeout = pull interval = 60s
   因为HTTP一般被用于短连接，通过连接超时实现复用。 当这3个参数相同的时候， 下一次pull， 获取连接， 可能刚好 server 关闭了连接， client未感知到， 使用这个连接发生请求， 就会出现偶然错误。 
   
   默认pull interval 是 30s， 只要请求不超时， 基本可以保证链接可以持续复用， 那么概率会降低很多。 理论上3个值分别为 50s , 60s, 30s ，保证 client < server， 那么发生的概率会更小。 
   
    pull interval > client idle > server idle 的情况，概率最高。
