After rebuilding the schema file for the configuration database, the management process (mgd) closes the file and reopens it in read-only mode to prevent corruption. It could not reopen the file. The JUNOS command-line interface (CLI) and management process (mgd) together form the JUNOS user interface that accepts and processes input from users and client applications.
The UI_DBASE_REOPEN_FAILED message is logged each time the management process fails in its attempt to reopen the configuration database in read-only mode.
When a UI_DBASE_REOPEN_FAILED event occurs, a message similar to the following is reported:
mgd: UI_DBASE_REOPEN_FAILED: Reopen of the database failed
The cause of the UI_DBASE_REOPEN_FAILED event is due to an internal software failure occurring.
