I am trying to use the NUMA-aware implementation of ParallelScavenge GC of OpenJDK7 on a 8-node machine. Almost everytime I run it, I get a segmentation fault trying to access a page aligned address. The test is with DaCapo benchmarks which works fine with default setup. Although the address lies in the range of one of the lgrp's but in the memory maps, its not mapped anywhere. Can anyone please explain me what could be the problem. Please let me know if some additional information is needed.
