MOC_Parm_GcDt=ARFM4104I: Absent an override via the explicitGcPeriod cluster custom property, autonomic memory overload protection will wait {0} seconds between explicitly triggered garbage collections.
Explanation
Autonomic memory overload protection will explicitly trigger a garbage collection when the memory usage is high, unless this function is disabled or a full garbage collection has been done too recently.
User response
If the chosen interval is not good, set the explicitGcPeriod custom property on the cluster to indicate the desired interval; a value of zero disables this function.
