Hello,
Since restarting our web servers, librdkafka is failing to initialise. It's possible that PHP has been updated, but nevertheless it has been running PHP 7 throughout, and was working at one time. This is the error being logged in the apache error_logs:
PHP Warning: PHP Startup: rdkafka: Unable to initialize module\nModule compiled with build ID=API20151012,NTS\nPHP compiled with build ID=API20151012,TS\nThese options need to match\n in Unknown on line 0
Here's the current 'php -v' output:
PHP 7.0.18 (cli) (built: Apr 11 2017 14:25:57) ( NTS )
