SQLSTATE[HY000]: General error: 2006 MySQL server has gone away on running cron job magento

Question

I am working on Magento site and I get this error:

SQLSTATE[HY000]: General error: 2006 MySQL server has gone away on running 
cron job magento

Answer 1

I've encountered this error before. For my case it was due the database size is too large, more than 18gb for 5 years data.

The only solution that is working for me was to dump all those data and create a new database.
