"Probably the most important flag here would be GCHeapFreeLimit: simplified, if free space after full gc is below this percentage of total heap, that full gc does not count against GCOverHeadLimit." Total heap is the size given by -XX:MaxHeapSize. I.e. -XX:MaxHeapSize=9663676416 = 9216MB The total heap after full gc is e.g. 9043968K, i.e. 8832 MB. 1 - 8832/9216 = 4.17%.
