ARFM4108I

MOC_Parm_Nurs=ARFM4108I: Absent an override via the maxNonFullGcMemoryRelease cluster custom property, autonomic memory overload protection will figure a full garbage collection has happened when more than {0} kilobytes have been freed.

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; when a generational garbage collection technique is in use, a full garbage collection is detected when the memory usage drops by more than a lesser collection can free.

User response

If the chosen value is not good, set the maxNonFullGcMemoryRelease custom property on the cluster to indicate the critical amount of freed memory; a value of zero means every collection is deemed full, and a huge value means no collection (except those explicitly initiated by the protection function) will be deemed full.
