The database server ran out of log space in which to record this transaction. A transaction that is not fully recorded cannot be rolled back. To preserve database integrity, the database server ended the current operation that caused the long transaction.
Terminate the application and replan it so that it requires less log space in a transaction. Alternatively, contact the database server administrator to discuss increasing the number or the size of the logical logs. Be prepared to talk about the number of rows being updated or inserted and the size of each row.
