[keycloak-user] Unable to acquire JDBC Connection

Hi guys, I get this error: [0m [31m10:36:26,890 ERROR [org.hibernate.engine.jdbc.spi.SqlExceptionHelper] (default task-5447) javax.resource.ResourceException: IJ000453: Unable to get managed connection for java:jboss/datasources/KeycloakDS Caused by: org.hibernate.exception.GenericJDBCException: Unable to acquire JDBC Connection Caused by: javax.resource.ResourceException: IJ000655: No managed connections available within configured blocking timeout (30000 [ms]) I use Keycloak 4.4.0-Final and MySQL. I saw this: https://issues.jboss.org/browse/KEYCLOAK-3539 But it seems to be closed already. My application is very permission-intensive: on each API request (100 per second), I request Keycloak permission. That might be wrong design, maybe I should cache the permissions locally? Best, Corentin
