MOC_Parm_GcDtRel=ARFM4106I: Absent an override via the explicitGcPeriod cluster custom property, the time between explicit garbage collections for the purpose of memory overload protection will be relative to the configured time between successive settings of the memory overload protection control value in the On-Demand Configuration facility.
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.
