[keycloak-user] Keycloak caching issue

Hi, I have two Keycloak nodes (4.8.3) in standalone cluster mode. I have a load-balancer in front of them. I noticed that sometimes I am getting inconsistent RPTs meaning that I send two queries and the two RPTs returned have different granted permissions in them. So I wend behind the load-balancer and queried each node individually. It turns out that one of the nodes is always returning wrong set of permissions in RPT. If I go to the admin console and clear the realm cache, then both nodes would return the same correct permissions right away. This is so intermittent. I am not sure what is causing this. I cannot find any clue in the logs. There is not much out there. I do not know how to reproduce this. Anyone with similar issue? Any suggestions? Cheers Farzad
