MySQL Database Connection failing with latest Spigot Snapshot #26

Open

_ForgeUser26863716 created this issue Jan 13, 2017

When I today updated my Server from an older 1.11.2 Spigot Dev Build to the most recent one, suddenly the following Error occured everytime when Players finished an 1vs1 ´Duel. Seems like I have to switch back to Flatfile Storage now, because that Error produces massive Lag. Please fix!

[18:54:27] [Server thread/ERROR]: [1vs1] Error on saving player score
com.mysql.jdbc.exceptions.jdbc4.CommunicationsException: Communications link failure

The last packet successfully received from the server was 31,954,695 milliseconds ago. The last packet sent successfully to the server was 7 milliseconds ago.
