Also, we changed the new maintenance windows of the database to only on weekend days but the errors are still happening during week days.ĭoes anyone know what could be causing this sudden problem?

Yet then again, if the locks are short-lived and the locktimeout is set to 0, it should help with unsetting the locktimeout.

Since last week we have been getting many 'lock request time out period exceeded' errors in ADF in pipelines and data flows that connect to the SQL database: We have not had any troubles with this process until last week. We use Azure Data Factory to copy data from source systems to our Azure SQL Data Warehouse.
