Hi Team,
We notice below redis timeout error in application logs -
Redis LogRetryData - Retry operation. RetryCount = [1]. Sleep duration = [00:00:05]. Causing exception:
[StackExchange.Redis.RedisTimeoutException: Timeout performing HMGET (5000ms), next: HMGET 0f21kpmv0wrwvnntd5cf3ah2:Cache, inst: 1, qu: 0, qs: 26, aw: False, rs: ReadAsync, ws: Idle, in: 188, in-pipe: 35, out-pipe: 762, serverEndpoint:, mgr: 10 of 10 available, clientName: , IOCP: (Busy=48,Free=952,Min=4,Max=1000), WORKER: (Busy=49,Free=32718,Min=4,Max=32767), v: 2.0.601.3402 (Please take a look at this article for some common client-side issues that can cause timeouts: https://stackexchange.github.io/StackExchange.Redis/Timeouts)

A few articles found online suggested extending timeout on redis client using connectTimeout to more than default 5000ms. The timeout parameter was added in the connection string and set to 10000. Yet, we see the same type of timeout error referencing 5000ms.
Connection string for redis as follows-
; db=; port=6379; connectTimeout=10000; maxReadPoolSize=250; maxWritePoolSize=250; " />
Has anyone come across this issue before? Any insight is very much appreciated.
