Sever memory exhausted while run content deploy command and sever memory can't be increase then how to run content deploy command?
Before posting a question on Stack Exchange, please have a little look around first, you'll often find the question has already been asked/answered. Maybe just asked in a slightly different way.
See the answer from this post: Fatal error "Allowed memory size" while run setup:static-content:deploy
For clarity, i think what you're looking for is (taken from post mentioned above) you can set the memory limit inline whilst running the static content deploy command:
php -dmemory_limit=6G bin/magento setup:static-content:deploy
Hope this helps.
