Summary: (7.3.z) WFLY-13527 - Thousand of unauthorized requests in between
balancer and backend if backend is running in a cluster
Key: WFLY-13529
URL: https://issues.redhat.com/browse/WFLY-13529
Project: WildFly
Issue Type: Bug
Reporter: Ilia Vassilev
Assignee: Masafumi Miura
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}

*Note:* This behavior only occurs if there's more than a single backend server running
in a cluster...
