Error description

  • A query that involves the sysmaster table syslcktab with a where
    clause that includes the indx column will loop continuously and
    return no data with the value associated with the indx if the
    column is greater than or equal to the current size of the lock
    table. The query cannot be interrupted, nor the session killed,
    and the server must be restarted to remove it.
    
    Example:
    select * from syslcktab where indx = 20000
    
    If the value of the LOCKS onconfig parameter is 20000, and the
    lock table has not been extended, then the above query will
    hang. With a value of 19999 or less, the query will work as
    expected.
    
    The same problem will also occur when using a filter on the
    lk_id column of the syslocktab view.
