It worked fine as soon as I created the database with the newest version. But I'd like to be confident of BaseX that I won't lose my data as it happened for the version 6.1.
the database corruption you reported was most probably caused by an evil bug in the XQuery Update code that we were able to fix in version 6.2.8. It destroyed parts of the index structure, leading to reads on empty DB pages. The stack trace you provided is a result of that.
So I think the problem shouldn't happen again :-).
Cheers Leo
