Cause1: The lck file wasn't cleaned out during shutdown
The embedded HSQL Database places a *.lck file in BAMBOO_HOME/database folder when the database is being used. Its possible that the file wasn't deleted.
Cause2: The embedded HSQL database in BAMBOO_HOME/database/ folder is corrupted.
HSQL database is not recommended for production Bamboo instances as its susceptible for failures. It is mentioned on the Supported platforms page.
ソリューション
Resolution1: Clear out the lck file
Shutdown Bamboo and make sure there are no orphaned java/Bamboo processes running and delete the BAMBOO_HOME/database/*.lck file
Resolution1: Start with a new database
Install a fresh Bamboo instance and migrate to an external database
