StackExchange.Redis.RedisTimeoutException: Timeout exception response

Question

Our system uses Redis to save some data. Sometimes, on my application's insights I get a timeout exception like this:

Timeout awaiting response (outbound=0KiB, inbound=0KiB, 20640ms
elapsed, timeout is 20000ms), command=GET, active: GET
9ba45b00-52a6-41da-9acb-621665862a3b:UmsUserData, next: GET
0e730553-b6f5-4882-8c96-b853d549e385:UmsUserData, inst: 0, qu: 0, qs:
3, aw: False, rs: ComputeResult, ws: Idle, in: 1044, serverEndpoint:
Unspecified/azlink012.redis.cache.windows.net:6380, mgr: 9 of
10 available, clientName: RD0050F2931DEA, IOCP:
(Busy=1,Free=999,Min=100,Max=1000), WORKER:
(Busy=26,Free=32741,Min=100,Max=32767), v: 2.0.601.3402 (Please take a
look at this article for some common client-side issues that can cause
timeouts:

I have investigated some parameters like IOCP(1<100) and WORKER(26<100) and they are normal. What is the problem here?

I found my problem on GitHub.

if you are working with Redis, you should design your application such that it can handle connection blips. There are number of reasons due to which it can happen like failover, Redis patching etc.
