Need to understand Redis timeout exceptions

[ahashim123]

Hi I am using Redis nuget library version 2.7.4. We are seeing Redis timeout exceptions and its not clear what's the reason behind it.

Below are the errors that we are seeing on Production.

Timeout performing SET (10000ms), next: UNWATCH, inst: 0, qu: 0, qs: 0, aw: False, bw: SpinningDown, rs: ReadAsync, ws: Idle, in: 39, last-in: 0, cur-in: 0, sync-ops: 46187, async-ops: 1, serverEndpoint: xxx, conn-sec: 830305.23, aoc: 0, mc: 1/1/0, mgr: 10 of 10 available, clientName: xxxSE.Redis-v2.7.4.20928), IOCP: (Busy=7,Free=93,Min=20,Max=100), WORKER: (Busy=18,Free=82,Min=30,Max=100), v: 2.7.4.20928 (Please take a look at this article for some common client-side issues that can cause timeouts: https://stackexchange.github.io/StackExchange.Redis/Timeouts)

Another error,

The message timed out in the backlog attempting to send because no connection became available, command=EXEC, timeout: 10000, outbound: 0KiB, inbound: 0KiB, next: MULTI, inst: 3, qu: 0, qs: 0, aw: True, bw: WritingMessage, rs: ReadAsync, ws: Flushed, in: 0, last-in: 25, cur-in: 0, sync-ops: 46185, async-ops: 1, serverEndpoint: xxx conn-sec: 830294.4, aoc: 0, mc: 1/1/0, mgr: 10 of 10 available, clientName: xxx(SE.Redis-v2.7.4.20928), IOCP: (Busy=5,Free=95,Min=20,Max=100), WORKER: (Busy=17,Free=83,Min=30,Max=100), v: 2.7.4.20928 (Please take a look at this article for some common client-side issues that can cause timeouts: https://stackexchange.github.io/StackExchange.Redis/Timeouts)
