DB Vista -921 recovery

This error happens when a DB Vista tool has logged on to the database but crashed before logging off, leaving the user permanently logged on.

Note: Pressing Ctrl+C when an hcidbdump command is running can cause this error.

To resolve the issue on UNIX, use the lmclear -u TEST -mp command.

On Windows, stop all processes and daemons. Restart the system from Control Panel > Administrative Tools > Services.
