2.17. Connection to the Database is Lost if the Host Disk is Full (Bug ID 15921366)

If the disk that hosts the Oracle VDI database is full, the connection to the database is lost. The issue can affect both the embedded MySQL database and remote databases, and can result in a failover.

The Cacao logs contain the following error:

Internal Exception: java.sql.SQLException: Got error 28 from storage engine 
Error Code: 1030

The solution is to ensure that your hosts have sufficient free disk space. If you are using the embedded MySQL database, the database is located at /var/opt/SUNWvda/mysql.
