> 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.
