Bug Report

First of all: Have you checked the docs https://github.com/lettuce-io/lettuce-core/wiki, GitHub issues, or Stack Overflow whether someone else has already reported your issue?

In high concurrency call stringRedisTemplate. OpsForSet () members (Product_Source_Resource_ApplicationId + deviceKey); Always appear abnormal, when I want to check whether the key is first call stringRedisTemplate. HasKey (key) and there will be a new exception

Current Behavior

A clear and concise description of the behavior.

See https://stackoverflow.com/help/minimal-reproducible-example for details of what a good minimum reproducible example is

Hey @DaPeng-Zong ,

not sure how I can help here. What code causes this issue? Is it reproducible? Can we have a minimal reproducible example where we can see the problem manifest?

By the way there is a template for filing new bugs, have you considered filling it up?

By the way, as per #2175 the ValueOutput does not support set(long) issue might be caused when an internal issue happens in the driver, and I see a NullPointerException before that, but we are missing the full stack trace as it says

Caused by: org.springframework.data.redis.RedisSystemException: Unknown redis exception; nested exception is java.lang.NullPointerException
...
... 22 more

and we are missing the actual cause (that might point us to the NPE that might have caused all the other exceptions

@tishun tishun changed the title In high concurrency call stringRedisTemplate. OpsForSet () members (Product_Source_Resource_ApplicationId + deviceKey); Always appear abnormal, when I want to check whether the key is first call stringRedisTemplate. HasKey (key) and there will be a new exception In high concurrency call stringRedisTemplate fails Jan 2, 2025

FWIW, out of sync issues have been observed in OOM scenarios:

The above problem may occur after a period of time after the occurrence of OOM

via spring-projects/spring-data-redis#3077 (comment)

I wonder whether CommandHandler.exceptionCaught(…) should terminate its connection and complete commands exceptionally once it has seen a java.lang.Error. Maybe this could help in addressing out of sync errors.
