I have a application with several independant modules with each teir own database (registered as additional datastores). When one of these goes offline, the whole application crashes with the following log:
Connection Pool-dbBalanceadosSiemens - Failed to validate connection com.mysql.cj.jdbc.ConnectionImpl@3715a6b5 (No operations allowed after connection closed.). Possibly consider using a shorter maxLifetime value.
Is there any way to prevent this, say give timeout error on screens related to these entitites?
