[keycloak-user] Problem when we execute storage provider SPI in domain mode.

We have created a storage provider SPI with keycloak-2.2.1.Final but we have a problem when we execute this SPI in domain mode. We use a postgres XADatasource and we create the SPI in the same way as the storage provider example. We have a master with a single slave. When we ask for a token we have the following error: The pre-jca synchronization org.jboss.as.ejb3.component.stateful.StatefulSessionSynchronizationInterceptor$StatefulSessionSynchronization@3a417315 associated with tx TransactionImple < ac, BasicAction: 0:ffffc0a83866:-33c4bf71:5910ee3a:da status: ActionStatus.ABORTED > failed during after completion: java.lang.IllegalStateException: Transaction DummyTransaction{xid=DummyXid{id=11}, status=1} is not in a valid state to be invoking cache operations on……. And org.infinispan.util.concurrent.TimeoutException: ISPN000299: Unable to acquire lock after 10 seconds for key f:96007b81-fe12-491d-9a7f-c0bfabc8345a:name.lastname and requestor GlobalTransaction:<null>:13:local. Lock is held by GlobalTransaction:<null>:10:local….. (you can see the complete trace in log.log, adjunted in this e-mail) ------- we’ve applied the solution of http://lists.jboss.org/pipermail/keycloak-user/2016-October/007901.html but when we do a lot of requests we have an error with the entity manager. 12:20:20,203 ERROR [io.undertow.request] (default task-13) UT005023: Exception handling request to /auth/realms/Latam-Realm/protocol/openid-connect/token: org.jboss.resteasy.spi.UnhandledException: org.keycloak.models.ModelException: java.lang.IllegalStateException: EntityManager is closed [Server:server-one] at org.jboss.resteasy.core.ExceptionHandler.handleApplicationException(ExceptionHandler.java:76) [Server:server-one] at org.jboss.resteasy.core.ExceptionHandler.handleException(ExceptionHandler.java:212) [Server:server-one] at org.jboss.resteasy.core.SynchronousDispatcher.writeException(SynchronousDispatcher.java:168) [Server:server-one] at org.jboss.resteasy.core.SynchronousDispatcher.invoke(SynchronousDispatcher.java:411) [Server:server-one] at org.jboss.resteasy.core.SynchronousDispatcher.invoke(SynchronousDispatcher.java:202) [Server:server-one] at org.jboss.resteasy.plugins.server.servlet.ServletContainerDispatcher.service(ServletContainerDispatcher.java:221) [Server:server-one] at org.jboss.resteasy.plugins.server.servlet.HttpServletDispatcher.service(HttpServletDispatcher.java:56) [Server:server-one] at org.jboss.resteasy.plugins.server.servlet.HttpServletDispatcher.service(HttpServletDispatcher.java:51) [Server:server-one] at javax.servlet.http.HttpServlet.service(HttpServlet.java:790) [Server:server-one] at io.undertow.servlet.handlers.ServletHandler.handleRequest(ServletHandler.java:85) [Server:server-one] at io.undertow.servlet.handlers.FilterHandler$FilterChainImpl.doFilter(FilterHandler.java:129) [Server:server-one] at org.keycloak.services.filters.KeycloakSessionServletFilter.doFilter(KeycloakSessionServletFilter.java:90) [Server:server-one] at io.undertow.servlet.core.ManagedFilter.doFilter(ManagedFilter.java:60) [Server:server-one] at io.undertow.servlet.handlers.FilterHandler$FilterChainImpl.doFilter(FilterHandler.java:131) [Server:server-one] at io.undertow.servlet.handlers.FilterHandler.handleRequest(FilterHandler.java:84) [Server:server-one] at io.undertow.servlet.handlers.security.ServletSecurityRoleHandler.handleRequest(ServletSecurityRoleHandler.java:62) [Server:server-one] at io.undertow.servlet.handlers.ServletDispatchingHandler.handleRequest(ServletDispatchingHandler.java:36) [Server:server-one] at org.wildfly.extension.undertow.security.SecurityContextAssociationHandler.handleRequest(SecurityContextAssociationHandler.java:78) [Server:server-one] at io.undertow.server.handlers.PredicateHandler.handleRequest(PredicateHandler.java:43) [Server:server-one] at io.undertow.servlet.handlers.security.SSLInformationAssociationHandler.handleRequest(SSLInformationAssociationHandler.java:131) [Server:server-one] at io.undertow.servlet.handlers.security.ServletAuthenticationCallHandler.handleRequest(ServletAuthenticationCallHandler.java:57) All of this only happen when we use domain mode with different slaves. But in standalone mode in local machines works perfectly.
