调研方向

从 ConnectionMultiplexer.cs:2037 开始,将报告的连接状态与 Redis 重启前后的 Redis CLI 客户端列表进行比较。确认已部署的应用为何报告 StackExchange.Redis v2.7.10,尽管声明的依赖项是 2.8.22,并使用提供的 Docker 设置和连接字符串重现重新连接失败。完成的标准是确定不可用连接的原因,并记录可靠的恢复路径。

描述

💬 needs-info

Hi everyone, I have a net8 api project that runs locally. Through docker deployment, Redis Serve is also deployed in docker on the same host.

StackExchange.Redis Version 2.8.22

The connection string in the code is as follows

"127.0.0.1:6379,DefaultDatabase=0,allowAdmin=true,abortConnect=false,connectRetry=5,connectTimeout=3000,syncTimeout=3000,asyncTimeout=3000,name=MesBus_Api,keepAlive=30"

Under normal circumstances, I will see two client connections named MesBus_Api in Redis Serve.looks like this

id=48 addr=127.0.0.1:35494 laddr=127.0.0.1:6379 fd=14 name=MesBus_Api age=8 idle=0 flags=N db=0 sub=0 psub=0 ssub=0 multi=-1 qbuf=0 qbuf-free=20474 argv-mem=0 multi-mem=0 rbs=1024 rbp=60 obl=0 oll=0 omem=0 tot-mem=22272 events=r cmd=setex user=default redir=-1 resp=2
id=49 addr=127.0.0.1:35496 laddr=127.0.0.1:6379 fd=15 name=MesBus_Api age=8 idle=7 flags=P db=0 sub=1 psub=0 ssub=0 multi=-1 qbuf=0 qbuf-free=0 argv-mem=0 multi-mem=0 rbs=1024 rbp=0 obl=0 oll=0 omem=0 tot-mem=1856 events=r cmd=subscribe user=default redir=-1 resp=2

But from time to time I encounter the following error:

StackExchange.Redis.RedisConnectionException: No connection is active/available to service this operation: HMGET MesBus:TokenBLK:2b290cab2815ab802a7e18e01bf679e1, inst: 0, qu: 0, qs: 0, aw: False, bw: SpinningDown, rs: ReadAsync, ws: Idle, in: 0, in-pipe: 0, out-pipe: 0, last-in: 2, cur-in: 0, sync-ops: 72, async-ops: 227416, serverEndpoint: 127.0.0.1:6379, conn-sec: 4370.5, aoc: 1, mc: 1/1/0, mgr: 10 of 10 available, clientName: hc-phytiumft20004(SE.Redis-v2.7.10.12442), IOCP: (Busy=0,Free=1000,Min=8,Max=1000), WORKER: (Busy=3,Free=32764,Min=16,Max=32767), POOL: (Threads=12,QueuedItems=0,CompletedItems=1155132,Timers=11), v: 2.7.10.12442
at StackExchange.Redis.ConnectionMultiplexer.ThrowFailed[T](TaskCompletionSource`1 source, Exception unthrownException) in /_/src/StackExchange.Redis/ConnectionMultiplexer.cs:line 2037

When I got this exception, I found that my project could not reconnect to the redis server correctly, and I used redis cli to check that the server had no slowlog, and the server was working normally (I have two programs written in rust that also use the redis server, both using db0)

Moreover, I checked the client list and there are still two MesBus_Api connections. When I restart the redis server, I can see that there is a MesBus_Api connection and my API project still tries to initiate a connection to redis because I detect that there is a TCP connection in my server to the Redis server, although They all end up as Time_Wait and they are unable to establish a normal connection to redis. Unless I restart my API project, at this point I can see that two connections named MesBus_Api have been established in redis. And the exception disappears in the project and all code works normally.

How should I troubleshoot or check this issue? Thank you for your help.
ps.I checked the server's CPU usage and it wasn't too high.
