【Azure Redis 缓存】Redission客户端连接Azure:客户端出现 Unable to send PING command over channel
问题描述
Redission客户端连接Azure:客户端出现 Unable to send PING command over channel ... ... io.netty.channel.StacklessClosedChannelException: null at io.netty.channel.AbstractChannel$AbstractUnsafe.write(Object, ChannelPromise)(Unknown Source)
问题解答
这个问题主要是 StacklessClosedChannelException Channel 已经关闭,在 pingConnectionInterval 设定的时间内无法获取到Redis服务心跳返回(PING/PONG), 主要的排查方向为检查 客户端 到 Redis服务端 的网络状态。
