Due to cgroupsv2 enabled by default in OpenShift 4.14, the automatic heap size calculation seems to be broken in the latest RH-SSO image at this time.
The issue is caused by /opt/jboss/container/java/jvm/container-limits script which is called during container startup. It's already fixed in cct_module 0.45.6.
The same issue in EAP based products has been fixed on JBEAP-26130 and RHPAM-4777. So if possible, please update cct_module from 0.45.5 to 0.45.6 in the next RH-SSO container release.
Steps to reproduce
Expected: -Xms 128m -Xmx512m
Actual: -Xms1303m -Xmx1303m
