I am using AF SDK to copy production databases over to a test environment. For setting up the database structure in PI AF, im exporting the prod databases as an xml and importing them with ImportXml(object importObject, PIImportMode importMode, XmlReader reader, EventHandler<AFProgressEventArgs> eventHandler); The other day this was working perfectly. Recently, the function executed, processes everything properly until it gets to an AFElement, where it gets stuck on "Processing AFElement 'ExampleElem'". It takes about 1 minute per element to be processed, and importing manually within PSE works fine. Previously the AF SDK method finished in about 30 seconds per database.
