When detailing down into a form or screen, the resources used are locked. If you do not log out of Colleague (e.g. you close the window without clicking *log out*), the resource will remain locked for anywhere from 15 to 30 minutes before the session or lock expires. This can also happen if there is a SQL or Colleague script error that interrupts a save. You can use **LRCS** to unlock users, forms, and screens.

For more information, including the SQL query to investigate and unlock, see [Ellucian Hub Article #000005834](https://ellucian.force.com/clients/s/article/9088-How-to-find-and-kill-a-SQL-lock).
