[jboss-jira] [JBoss JIRA] (WFWIP-206) scale down isn't successful when there are in-doubt transaction on pod

scale down isn't successful when there are in-doubt transaction on pod ---------------------------------------------------------------------- Key: WFWIP-206 URL: https://issues.jboss.org/browse/WFWIP-206 Project: WildFly WIP Issue Type: Bug Components: OpenShift Environment: operator, built from [1984d98154f11a7473be065e4ae7f54b1812c9b0|https://github.com/wildfly/wildf...] : {noformat} docker-registry.engineering.redhat.com/jbossqe-eap/wildfly-operator:latest {noformat} EAP image: {noformat} docker-registry.engineering.redhat.com/ochaloup/wildfly18-snapshot:190909... {noformat} Reporter: Martin Simka Assignee: Ondrej Chaloupka Priority: Blocker Labels: operator While testing tx recovery in OpenShift I see that scale down of pod that has transaction in-doubt on it isn't successful Scenario: *ejb client* (app tx-client, pod tx-client-0): * EJB business method ** lookup remote EJB ** enlist XA resource 1 to transaction ** enlist XA resource 2 to transaction ** call remote EJB *ejb server* (app tx-server, pod tx-server-0): * EJB business method ** enlist XA resource 1 to transaction ** enlist XA resource 2 to transaction ejb server XA resource 2 fails with {{XAException(XAException.XAER_RMFAIL)}} Then the test calls scale down (size from 1 to 0) on tx-server pod. But scale down never completes.
