Hi Hilmar, Thank you for your response. I have checked this issue under TeXLive 2019 as of July 18 (installed by "install-tl") under ubuntu 19.04 (not debian/ubuntu packages)
The memory consumption of the latex file included in this bug report was "only" 1.8 GB after rm -rf ~/.texlive2019. Noto CJK fonts versions are those of ubuntu 19.04 (not the latest ones). It was 6 GB when I filed this report. Maybe 32-bit Linux can now handle the Noto CJK fonts. At least we can say significant improvement is in the upstream, though 1.8 GB seems a bit larger than necessary... I again compiled the same latex file by xelatex, but the processing finished immediately and I could not see the memory consumption by "top"...
