Recurring Console Error. #379

Closed PersonalDom closed 2 years ago

PersonalDom commented 2 years ago

Periodically I keep getting this error in console. 

[13:58:32 ERROR]: com.mysql.jdbc.exceptions.jdbc4.CommunicationsException: The last packet successfully received from the server was 50,377,147 milliseconds ago.  The last packet sent successfully to the server was 50,377,147 milliseconds ago. is longer than the server configured value of 'wait_timeout'. You should consider either expiring and/or testing connection validity before use in your application, increasing the server configured values for client timeouts, or using the Connector/J connection property 'autoReconnect=true' to avoid this problem.

Anyone know how I fix this?

This doesn't look related to SLP. You should contact the author(s) of the "StaffBungee" plugin.

PersonalDom commented 2 years ago

Ah, sorry about that. I'm not sure where you can tell what plugin the error is from lol.

stephan-gh commented 2 years ago

Just scan the error for plugin names:
