checkdba - Check the JOIN IP address lease database for internal con-
The checkdba command checks the records that comprise the DHCP IP address
lease database for internal consistency and prints inconsistent records to
standard out (stdout). If the database is consistent, the exit code is
zero, otherwise nonzero.
The database should never normally be in an inconsistent state, but can
become so if joind terminates abnormally before it can flush its internal
pages to disk. Program errors aside, this can only happen on receipt of a
signal that cannot be caught or ignored.
