I did actaully mention that before: | I am running a fake-numa=4 config on this test VM so it's got 4 | nodes of 4p/4GB RAM each. but I think it got snipped before Mel was cc'd. Perhaps size of the nodes is relevant, too, because the steady state phase 3 memory usage is 5-6GB when this problem first shows up, and then continues into phase 4 where memory usage grows again and peaks at ~10GB....
