When running and managing a multi-tenant server, that’s normally ran using WHM / cPanel, there’s a percentage of customers whom never check there website for errors, and another smaller percentage that don’t even update, as such these error logs can sometimes take up significant space on the server – and cause slowdowns with log writing applications such as logrotate and Apache,
A simple one liner is my usual go-to when finding things on a server and this one is no different, using bash execute the following command
find /home -name error_log -exec ls -lh {} + | sort
I added a small benefit to also sort them based on size so you can remove the largest ones first after investigating of course.
