92% chunk asset optimization - webpack
I too faced similar issue while running build remotely,So, in jenkin after adding following command, problem got resolved for me.
export "NODE_OPTIONS=--max_old_space_size=2000"
I do a yarn cache cleaning and it fixed my issue "92% chunk asset optimization TerserPlugin" on my Ubuntu 16.04 host on google cloud.
Not sure if it works on your machine
yarn cache clean
I have this issue on 2nd machine, and this machine requires a reboot.
sudo reboot
