[Carbon-dev] Exception seen when executing performance tests on Windows
Hi, I see the following exception when executing G-Reg performance tests on Windows. Is this simply because the connection has been lost with mySQL DB? Note that I have connected the user store DB to mySQL. *** The last packet successfully received from the server was 984 milliseconds ago. The last packet sent successfully to the server was 984 milliseconds ago. com.mysql.jdbc.exceptions.jdbc4.CommunicationsException: Communications link failure The last packet successfully received from the server was 984 milliseconds ago.
