This may be related to something else. Can you try again to create such a list, but before you do, please make sure that all song context panes (matching songs, album info, amazon) are closed. Preferably, you start beaTunes, close all those context panes, restart beaTunes and then create that large playlist.
Did a huge selection of about 19K songs, then "create playlist." I get a pop-up error saying: "org.hibernate. TransactionException: Transaction not successfully started." I clear this error and selected files continue to blink about once per second. This time I was able to shut down. Re-started BeaTunes and... there is a playlist "untitled" but it has 0 items. Uploaded logs. Happy troubleshooting!
