Can't enable production mode.

[olukyanenko]

I have:
Magento 2.1.2 in developer mode

When I try to switch it to production mode "php bin/magento deploy:mode:set production" I got an error
"Command returned non-zero exit code:
`/usr/bin/php5 -f /data/magento_store/magento2/magento_store/bin/magento setup:static-content:deploy en_US zh_Hant_HK`"

When I try 'magento setup:static-content:deploy en_US zh_Hant_HK' it completed without errors.

I have rechecked permissions, It's OK.

I try this command under the "root" user. Same error.

PHP 5.6.27-0+deb8u1
Apache/2.4.10 (Debian)
mysqld 5.6.34

Please give me any clue what is wrong?

One more thing

When enable to production failed. Any CLI command showed error

We're sorry, an error occurred. Try clearing the cache and code generation directories. By default, they are: var/cache, var/di, var/generation, and var/page_cache.

 Remove files from "var/cache, var/di, var/generation, and var/page_cache" fixed this issue

I have solved this issue by removing Migration Tools

composer remove magento/data-migration-tool --update-with-dependencies
