Additional information

  1. The issue does not occur when running on kernel version 5.14.0-383.el9.x86_64.
  2. The issue is present when running on kernel version 5.14.0-533.el9.x86_64
  3. The issue happens in production systems after running for 1 or 2days
  4. Redis server is running in cluster mode.
  5. Redis server is running in docker container and multiple containers are bin packed to the same baremetal host.
  6. In clusters, where we upgraded kernal of Baremetal host of a single redis server instance to version 5.14.0-533.el9.x86_64, the crash repeatedly occurs to the containerized redis instance once every 1-2 days. The rest of the containerized redis instances running on kernel version 5.14.0-383.el9.x86_64 have no issues.
  7. Heap usage is at 20-30% when the crash occurs.
  8. There is no activity logged in redis logs right before the crash (the previous logged activity is an AOF rewrite logged several minutes ago )
  9. Additional crashes

**Comment From: sundb**

@roshanphilips can you share the fully crash report, there should be something like '------ DUMPING CODE AROUND EIP ------' under the crash log you posted.
and can you share the binary with me(debing.sun@redis.com)?

**Comment From: sundb**

similar issues: https://github.com/redis/redis/issues/10739, https://github.com/redis/redis/issues/8254

**Comment From: roshanphilips**

@sundb , thank you for the quick response. Some of the crashes doesn't log ` DUMPING CODE AROUND EIP...` However for the following crash, `DUMPING CODE AROUND EIP...` was logged

@roshanphilips Does your server have such a large amount of memory? total_system_memory_human:1.48T

Comment From: roshanphilips
