Legacy EJB Client: High fail rate --------------------------------- Key: WFLY-11292 URL: https://issues.jboss.org/browse/WFLY-11292 Project: WildFly Issue Type: Bug Components: Clustering, EJB Affects Versions: 15.0.0.Beta1 Reporter: tommaso borgato Assignee: Flavia Rainone Priority: Blocker Attachments: jboss-ejb-client.properties, logs-10clients.zip, logs.zip This bug is being filed as Blocker because we are observing and elevated fail rate: roughly a thousand each run for (about 0.3%). h2.
