2 months ago Hey @FrankCy, from the stacktrace I can only assume you are having issue with the Spring Data Redis and not the Lettuce drive itself? Perhaps this issue would be better suited there?

Current Behavior
Configured LettuceClientConfiguration and set topology refresh, but in high concurrency scenarios, occasionally prompts this error, would like to help analyse the cause, thanks.
