Hi Rick, Thanks for your observations.
I restricted my main memory to 2 GB and I played around with your sample data (with Windows). My memory consumption never exceeded 200 MB (and after closing everything, it goes back to appr. 30 MB). Maybe there is a single operation that I missed? If the limits for query results have been increased in the GUI Preferences (in the "Result" tab), memory consumption might rise as well. If you have not changed the defaults, you could help us by… • opening the "Used Memory" dialog (I think you have done this already, right?) and • clicking the "GC" after each single action you perform. If the "Used Memory" value rises a lot after a specific action even after garbage collection, and if it doesn’t decrease after closing the database, your editor tabs, visualizations, etc., then you might have been able to isolate the operation that leads to the observed memory leak. If you believe that the visualizations might affect memory consumption, you can close them if a database is opened, and restart BaseX (visualizations won’t be computed if they are not displayed). Feel free to provide us with a list of the actions and the values for the observed memory consumption. Best, Christian
