An operating-system error code with the meaning shown was unexpectedly returned to the database server. This implementation of the IBM Corporation database server probably uses kernel locking, the use of the operating-system facilities to lock rows of tables. The capacity of the operating-system lock table has been exceeded. Contact your system administrator and inquire about configuring the operating system to support more locks. Also examine your database application to see if it can use fewer locks by updating fewer rows in each transaction or by locking whole tables instead of rows.
