Re: [keycloak-user] how to clean-up OFFLINE_CLIENT_SESSION, OFFLINE_USER_SESSION tables

Thank you for your message. However, if I set parameter "Offline Session Idle" to 30 min, I am getting a replication timeout exception associated with the periodic cleaner scheduler service [Server:server-one] 09:24:54,979 ERROR [org.keycloak.services] (Timer-2) KC-SERVICES0089: Failed to run scheduled task ClearExpiredUserSessions: org.infinispan.util.concurrent.TimeoutException: Replication timeout for slaveServer:server-two [Server:server-one] at org.infinispan.remoting.transport.jgroups.JGroupsTransport.checkRsp(JGroupsTransport.java:765) [Server:server-one] at org.infinispan.remoting.transport.jgroups.JGroupsTransport.lambda$invokeRemotelyAsync$72(JGroupsTransport.java:599) [Server:server-one] at java.util.concurrent.CompletableFuture.uniApply(CompletableFuture.java:602) [Server:server-one] at java.util.concurrent.CompletableFuture$UniApply.tryFire(CompletableFuture.java:577) [Server:server-one] at java.util.concurrent.CompletableFuture.postComplete(CompletableFuture.java:474) [Server:server-one] at java.util.concurrent.CompletableFuture.complete(CompletableFuture.java:1962) [Server:server-one] at org.infinispan.remoting.transport.jgroups.SingleResponseFuture.call(SingleResponseFuture.java:46) [Server:server-one] at org.infinispan.remoting.transport.jgroups.SingleResponseFuture.call(SingleResponseFuture.java:17) [Server:server-one] at java.util.concurrent.FutureTask.run(FutureTask.java:266) [Server:server-one] at java.util.concurrent.ScheduledThreadPoolExecutor$ScheduledFutureTask.access$201(ScheduledThreadPoolExecutor.java:180) [Server:server-one] at java.util.concurrent.ScheduledThreadPoolExecutor$ScheduledFutureTask.run(ScheduledThreadPoolExecutor.java:293) [Server:server-one] at java.util.concurrent.ThreadPoolExecutor.runWorker(ThreadPoolExecutor.java:1142) [Server:server-one] at java.util.concurrent.ThreadPoolExecutor$Worker.run(ThreadPoolExecutor.java:617) [Server:server-one] at java.lang.Thread.run(Thread.java:745) This exception is thrown with a periodicity of 15 min. I have found a previous reference to such exception in your "keycloak-user" customer inquiries http://lists.jboss.org/pipermail/keycloak-user/2016-July/006892.html It looks like there was a bug in your KC software. Have you fixed this bug in your later KC releases since July 2016? Or, it may be a miss-configuration in my domain clustered configuration( I use your KC-2.1.0.Final release) ?

There is periodic cleaner, which will remove the records from the expired offline sessions. But timeout for the offline sessions is 30 days by default. Also the time of "last refresh" is currently updated in DB every time when you restart the server (in case that you have single-server without cluster). In other words, if you restart the server at least once every 30 days, the table will keep growing. It is probably something we can improve... Feel free to create JIRA. Until that, your possibilities are: - Decrease the timeout to shorter value than 30 days (can be done in admin console) - Ensure the server is not restarted within 30 days, so the outdated sessions can be cleared. - Use cluster with 2 nodes or more and ensure that at least 1 node is always online.
