Describe the bug
This is the bug I keep getting, when I load my Spring Application:

This always happens when I load Spring Boot. Can someone help?

Hi @dreamstar-enterprises, thanks for the report.

This problem seems related to Spring Data Redis. Did you try to use only Spring Data Redis (without Spring Session) and connect to the Redis instance to confirm whether this is a Spring Session bug??

I ran this in Docker compose and do not get the same error? Why is that?

No errors even after 6 minutes...

It's intersting too that I don't get the error in debug mode, so setting a breakpoint does not help since it doesn't trigger in debug mode. The Actuator Health Check also doesn't run in debug mode.
But I consistently get the error, when I start in run mode.

The root cause seems to be a SocketException, looking at the error call stack
