We got this error:
-- Msg 9002, Level 17, State 4, Procedure sp_xxx, Line nn
-- The transaction log for database 'dbdbdbdb' is full. To find out why space in the log cannot be reused, see the log_reuse_wait_desc column in sys.databases
It seems to have been caused by lack of physical space on the Server's drive in this case so I suggest check that as well.
