Unable to load dynamic library '/usr/local/opt/php71-intl/intl.so'

The fix is actually quite easy. Since the library is now in the core of PHP and should be managed using pecl. One should delete the include in the conf.d directory of the PHP version you're running. E.G: For PHP 7.1 I would remove the following:

/usr/local/etc/php/7.1/conf.d/ext-intl.ini

Study case: "InnoDB: Database was not shutdown normally! "

The out-of-memory killer would choose mysql to close down, because it was (usually) the biggest memory user in the system.

The command to sort down processes by memory usage:

ps aux --sort -rss | head -n15

Solution:

  • Try upgrade new version
  • Turn off optimize performance schema, edit /etc/mysql/my/cnf
