conexión perdida a mysql
New versions of MySQL WorkBench have an option to change specific timeouts.
1.For me it was under Edit → Preferences → SQL Editor → DBMS connection read time out (in seconds): 600
Changed the value to 6000.
2. uncheck limit rows in in Edit → Preferences →SQL Queries
Also unchecked limit rows as putting a limit in every time I want to search the whole data set gets tiresome.
