Answer 1

Removed your var/generation directory and var/cache directory.

You need to remove it manually, if it is ubuntu then locate in your magento 2 root directory and run rm -rf var/generation and rm -rf var/cache command.

Then try to run below commands in sequence.

• php bin/magento setup:di:compile
• php bin/magento setup:upgrade
• php bin/magento cache:clean
• php bin/magento cache:flush

Answer 2

If production mode, put site into maintenance mode first.

bin/magento maintenance:enable
bin/magento setup:upgrade
bin/magento setup:di:compile
bin/magento setup:static-content:deploy
bin/magento cache:flush
// If running as root instead of www-data for example you may need to chown/chmod.
// chown -R www-data:www-data .

bin/magento maintenance:disable

Maybe it is because stuff is being generated as bots/users try to access the site?

Note: If you use other locales you would want to setup:static-content:deploy those as well.

I think you can specify multiple after the statup:static-content:deploy en_US en_GB en_NZ etc...

You might need to take ownership of the folder first or shell in as the Magento filesystem owner.
