In high concurrency call stringRedisTemplate fails

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

Expected behavior/code

A clear and concise description of what you expected to happen (or code).

Environment

e.g.

  • Lettuce version(s): [e.g. 5.0.0.RELEASE, 4.2.2.Final]
  • Redis version: [e.g. 4.0.9]

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?

tishun avatar Jan 02 '25 12:01 tishun

By the way, as per https://github.com/redis/lettuce/issues/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

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 https://github.com/spring-projects/spring-data-redis/issues/3077#issuecomment-2567231802

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.

#3132 should handle that.

@DaPeng-Zong , just to make sure you do not miss that - we are waiting for feedback from you.

I have encountered the same problem. Has anyone dealt with it?
