Hello,

this looks like network or MySQL Server related issue. Check if your network is stable between the Talend computer and MySQL, check if MySQL is in the correct state. Check if there are any performance issues on the MySQL server side.
This may happen if you have big tables, slow disk operations and a huge amount of data you want to insert. This may cause performance issue which leads to e.g. timeouts.
Another option. You can try is to generate e.g. CSV file with data you want to import and then use Bulk Import.
