@wyanglau Did you find any solution to this? We have very similar issue: [High CPU Utilization and Frequent Restarts after Upgrading from Keycloak 19 to Keycloak 22](https://forum.keycloak.org/t/high-cpu-utilization-and-frequent-restarts-after-upgrading-from-keycloak-19-to-keycloak-22/26298/1)

Heap dump indicates issue with Freemarker template engine but no idea if thats real culprit.
