Hi Philippe,
I remember we’ve fixed a bug like this 2, 3 years ago. BaseX 9.2.1 is pretty old now; do you have a chance to upgrade to BaseX 10.4 or at least BaseX 9.6.4?
I guess the problem should disappear if you run OPTIMIZE ALL or db:optimize(..., true()) and switch to the new version.
Hope this helps, cordiales salutations, Christian

Hi all,
I tried to replace a database in the BaseX Database Administration
(dba). A simple task that I often do.
But this time, I get this message:
