Redis每秒创建新连接并丢弃旧连接

• 问答

我们有一个具有3个节点的 Redis集群（以Sentinel模式运行），并且我们正在使用 Redisson （版本3.10.7）与Redis进行交互。 我们面临的问题是客户端应用程序无法连接到集群。持续旧连接被删除，新连接被创建。每秒钟发生同一件事。下面是记录器的快照。

我们尝试了以下几点来调查此问题：

  • 重新启动客户端应用程序。
  • 重新启动Redis群集节点。

也将这些重新发布发布，仍然存在相同的问题。

我们能够通过在Redis的server.conf中将 超时 属性从 0更改为10 秒来解决该问题。将超时恢复为0时，也不会导致问题再次发生。

还有其他人遇到类似的问题吗？如果是，我们知道其背后的原因吗？
