[jboss-jira] [JBoss JIRA] (WFLY-13527) Thousand of unauthorized requests in between balancer and backend if backend is running in a cluster

Thousand of unauthorized requests in between balancer and backend if backend is running in a cluster ---------------------------------------------------------------------------------------------------- Key: WFLY-13527 URL: https://issues.redhat.com/browse/WFLY-13527 Project: WildFly Issue Type: Bug Reporter: Flavia Rainone Assignee: Masafumi Miura Priority: Major A standalone client application is calling EJBs on a backend server through an Undertow loadbalancer. The client looks like this: {code:java} Properties props = new Properties(); props.put(Context.INITIAL_CONTEXT_FACTORY, WildFlyInitialContextFactory.class.getName()); props.put(Context.PROVIDER_URL, "http://10.0.0.1:9080/wildfly-services"); props.put(Context.SECURITY_PRINCIPAL, "some-user"); props.put(Context.SECURITY_CREDENTIALS, "some-password"); InitialContext ctx = new InitialContext(props); String name="ejb:/playground-jar/JBossManIntClientBean!org.jboss.playground.JBossManIntClient"; JBossManIntClient bean = (JBossManIntClient) ctx.lookup(name); {code} A client invoking the same EJB twice result in thousands of requests from the balancer to the backend servers, e. g.: * 13468 times: {code} INFO [io.undertow.accesslog] (default I/O-3) 10.0.0.1 - - [24/Sep/2019:12:03:03 +0200] "POST /wildfly-services/ejb/v1/invoke/-/playground-jar/-/JBossManIntClientBean/-/org.jboss.playground.JBossManIntClient/getHost HTTP/2.0" 401 77 "-" "-" Cookie: "-" Set-Cookie: "-" SessionID: - Thread: "default I/O-3" TimeTaken: 5063 {code} * 2 times: {code} INFO [io.undertow.accesslog] (default I/O-3) 10.0.0.1 - - [24/Sep/2019:12:06:53 +0200] "POST /wildfly-services/ejb/v1/invoke/-/playground-jar/-/JBossManIntClientBean/-/org.jboss.playground.JBossManIntClient/getHost HTTP/2.0" 200 155 "-" "-" Cookie: "-" Set-Cookie: "-" SessionID: - Thread: "default I/O-3" TimeTaken: 614 {code} *Note:* This behavior only occurs if there's more than a single backend server running in a cluster...
