redis键随机消失

我对redis有一个问题,它只出现在生产中,我不能在本地复制它。

我有11台服务器向redis发送数据,每台服务器增加一个散列映射的成员(每台服务器都有自己的散列映射)。

随机的时候散列映射消失了,我看到所有的计数都从0开始。

注意:

• 钥匙不是 期满 :任何密钥上均未设置过期或ttl;
• 钥匙不是 驱逐 以下内容: maxmemory 未设置并且 maxmemory-policy 是 no-eviction 无论如何;
• redis从来没有内存问题,因为它在一个有15gb空闲ram的服务器上,而且它从来没有崩溃过;
• INFO 报告13个连接的客户端,这是有意义的:11个服务器+1个本地监视应用程序+用于获取 信息 命令。

我不知道去哪里找了。

以下是 信息 命令:
