java process measured RAM by AIX keeps growing

This is the linux behavior similar to the AIX already posted https://gceasy.io/my-gc-report.jsp?p=c2hhcmVkLzIwMjEvMDcvNy8tLWp2bS10ZWxhLnppcC0tMTAtNDAtMjU=&channel=WEB. Big difference is that at Linux the measured RAM is flat, little variation around a medium value. At AIX the measured RAM keeps growing, a medium value cannot be seen!
