Sonarqube community 8.0 Analysis Bug

Hi,my sonarqube version is community edition 8.0 and my database is oracle12c. I didn’t do a version upgrade, I just migrated the application and database to the new machine. After the migration, an error message will occasionally appear. The error message is: Failed to perform DB migration for project…Caused by: java.sql.SQLRecoverableException: IO Error: Connection timed out… This kind of error occurs every few days. The same sonarqube project sometimes appears, sometimes not. How can I handle this? Should I upgrade the version, or can I migrate the database back to sonar’s internal database? Or upgrade the oracle driver?
