Is it reproducible with 3.16.5 version?

Can you try attached version? [redisson-3.17.8-SNAPSHOT.jar.zip](https://github.com/redisson/redisson/files/9775290/redisson-3.17.8-SNAPSHOT.jar.zip)

Fixed in https://github.com/redisson/redisson/commit/2e874b085a207d3977b7abdaea88020bf3932f47. Thanks for report

Can you share Redisson logs with `debug` tracing logging level? It's similar to a network issue

Can it be related to https://github.com/redisson/redisson/issues/3934 ?

Did you try to increase nettyThreads setting?

busy netty threads may cause these errors.

Unable to reproduce this issue. It might be environment specific. Can you share full log from application start?

Try to set masterConnectionMinimumIdleSize = masterConnectionPoolSize, slaveConnectionPoolSize = slaveConnectionMinimumIdleSize

In this case you need to increase retryAttempts amount to survive failover without errors.
