Describe the bug
Starting from Keycloak v26 we keeps getting the following exception in the logs. It doesn't seem to cause user-facing issues, but adds a lot of noise with our monitoring.

Version
26.2.4
Regression
[ ] The issue is a regression
Expected behavior
I would not expect the exception to occur such frequently and it should allow tracing the session update causing the issue better
Actual behavior
We get about 3-10 of this exception every day for the past 5 month (since v26 upgrade)
How to Reproduce?
I guess running a large enough instance with concurrent requests would trigger it?
Anything else?
No response
