-----------------------------------

             Summary: 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: MP Metrics
    Affects Versions: 16.0.0.Final
            Reporter: Bernd Stolle
            Assignee: Jeff Mesnil


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.
