We see test gc/TestAlwaysPreTouchBehavior.java#ParallelCollector failing on Linux, for example Linux ppc64le RHEL 9.3 .
But also failures on SLES 15.6 were seen, so it is not only a problem showing up on RHEL .
We get too low RSS reported, example :
----------System.out:(2/50)----------
RSS: 257884160
Host available memory: 45643202560
----------System.err:(13/1146)----------
java.lang.RuntimeException: RSS of this process(257884160b) should be bigger than or equal to heap size(268435456b) (available memory: 45643202560): expected 257884160 > 268435456
