[keycloak-user] Losing some sessions during clustering

Hello Keycloak users, We're seeing strange behavior with the session handling when starting up a new node. Keycloak doesn't retain all sessions. Here's our experiment: 1. start with 1 node containing a few dozen sessions 2. start node 2 (nodes clustered via JGroups Ping table + infinispan) 3. wait for 10 minutes 4. stop node 1 End result: *some* of the clients connected are forced to log back in. Most sessions remain. We're still investigating, so I cannot infer beyond this point at the moment. I'm simply curious whether anyone knows the following: - are *all* sessions meant to be migrated to new nodes? - how long does it take to migrate sessions? - does a new node wait until sessions are migrated before it enables the admin interface? - is there any logic to prune sessions on clustering? Any thoughts would be greatly appreciated. Thanks, Chris
