[jboss-jira] [JBoss JIRA] (WFLY-12167) Memory leak in metrics in standalone-ha configuration

Memory leak in metrics in standalone-ha configuration ----------------------------------------------------- Key: WFLY-12167 URL: https://issues.jboss.org/browse/WFLY-12167 Project: WildFly Issue Type: Bug Components: Clustering, MP Metrics Affects Versions: 16.0.0.Final Reporter: Bernd Stolle Assignee: Paul Ferraro Priority: Blocker Labels: memoryleak Attachments: Screenshot 2019-06-06 at 11.07.00.png When started in standalone HA configuration every request to the recently added metrics endpoint ({{<management-if>:9990/metrics}}) lead to an increase in memory consumption until the JVM is slowed down significantly by GC to a point where even the requests to {{/health}} fail within a reasonable timeout (2s) and untlimately lead to OOM. The same issue does not occur when WildFly is started in the default standalone configuration (non HA). I can provide a (compressed) heap dump if required.
