Description

We are getting below error in our Keycloak deployment, causing failures in transaction operations. Below is the error log for reference:

The issue seems to be related to the OFFLINE_USER_SESSION table and a Hibernate StaleStateException, indicating that batch updates are returning unexpected row counts. We have already reviewed our setup and implemented a distributed cache configuration to support multiple replicas. Below are the details of our environment and configuration:

Environment Details:

Keycloak Version: 26.0.7
Image Used: quay.io/keycloak/keycloak:26.0.7
Deployment Strategy: Custom Kubernetes deployment (not using the Keycloak operator)
Database: PostgreSQL
Replication Setup: Minimum of 2 replicas

Caching Configuration:
We followed the Keycloak documentation for distributed cache (Keycloak Server Caching) and made the following changes:

Modified cache-ispn.xml: Set owners=2 for all distributed-cache settings.
Arguments Passed to Start Keycloak:

args:
  - start
  - --cache=ispn
  - --cache-stack=kubernetes
  - -Djgroups.dns.query=keycloak-discovery.keycloak.svc.cluster.local
  - --spi-connections-infinispan-transport-stack=kubernetes
  - --features=persistent-user-sessions
  - --health-enabled=true
  - --metrics-enabled=true
  - --cache-metrics-histograms-enabled=true

Keycloak application starting logs:

Server configuration updated and persisted. Run the following command to review the configuration:

        kc.sh show-config

Next time you run the server, just run:

        kc.sh start --cache=ispn --cache-stack=kubernetes --spi-connections-infinispan-transport-stack=kubernetes --cache-metrics-histograms-enabled=true --optimized

Issue Summary:

The error appears to be related to the handling of the OFFLINE_USER_SESSION table. Despite implementing distributed caching for multi-replica support

Could you please assist in identifying the root cause of this issue and provide guidance on resolving it? Specifically:

Are there any additional configurations or optimizations required in our distributed caching setup?
Is there any known issue with the OFFLINE_USER_SESSION table when running multiple replicas of Keycloak?
Any recommendations for database-level settings to avoid table locks?

We look forward to your assistance and are happy to provide further details if required.
Thanks.

Are you going for a multi-site deployment, or single-site? The blog has some clarifications on which cache settings should be used in either case; perhaps that could help - https://www.keycloak.org/2024/12/storing-sessions-in-kc26.html. If you have an external Infinispan server for a multi-site deployment, you need to use the "cache-remote-store" settings and enable the "multi-site" feature.

From the logs, it seems that the Keycloak service does not see the other instances in the cluster (it creates a cluster by itself). This would imply that the Keycloak nodes do not synchronize using the caches. I think it could be normal when using an external Infinispan server, as the Keycloak instances can use that to sync, instead of clustering the embedded Infinispan instances.

I hope this helps to establishing that our keycloak instances are connected to an external postgres db.

The errors you see here occur when a user session is updated concurrently on two nodes. The loosing node will write those warnings, and then retry.

Unfortunately the warnings are always written by Hibernate. The Keycloak team asked the Hibernate team to remove that warning, but that will take another release of Hibernate, Quarkus and Keycloak.

Thank you very much @ahus1 for taking time to answer. So it means this error can be safely ignored? and you're working to reduce the verbosity of the logs with the Hibernate team? is that correct?

A "StaleStateException" of the persistent session worker will lead to a retry. Once the retry succeeds, there is no user-facing error. So it is ok to continue. Please continue to watch out for other errors.

It would be good to understand how/why in your setup those exceptions occur. The only explanation to me is that for the same user session there are multiple concurrent requests going on on different nodes of Keycloak. It would be good to understand in what scenarios they are happening, so we could reduce the number of those exceptions. In the end, each retry increases the load of the system, and slows down the response.

It seems version 26.1.0 changes the default discovery protocol to jdbc-ping, which should make things easier in cloud environments, according to the team - https://github.com/keycloak/keycloak/releases/tag/26.1.0. See if it works better for you.

Hi @darius-m - Thanks for your reply.

I tried running version 26.1.0 with multiple replicas (2) using the default arguments, but I'm encountering the same issue. For the database, I'm using a PostgreSQL database, and both replica instances are sharing the same database connection string. I'm not using keycloak.conf to manage the connection. Could you please help me resolve this issue?

- args:
            - start
            - --metrics-enabled=true

Hi,

we switched to keycloak 26.1.0 with jdbc-ping as cache stack. We have 2 instances of keycloak.

We are experiencing the same error from times to times:
