Tried the DB on the latest version and got the same error. Optimize all gave me this "create statistics...:undeclared namespace prefix"
Could you possibly add some more infos? Did you get this error with 7.9 or the latest version? Did the command complete successfully, or did it fail?
Maybe a corrupt namespace hierarchy in your database causes these errors. You could additionally try to…
1. Run the INSPECT command and see if it reports any errors. 2. Export your database (via the EXPORT command) and create a new database from the resulting directory.

Dear Jason,
As you already indicated by yourself, version 7.9 is a bit older, so it would be interesting if you can reproduce the problem with a newer version. You could additionally try to optimize your database (using OPTIMIZE ALL or db:optimize(..., true()) ) and give us some feedback if the problem persists.
Best, Christian

I am running BaseX 7.9 (yes I know its old but for reasons beyond the scope of this we can't just update BaseX) on RHEL 6.9.
The BaseX is not running any instance as a server but as a standalone application with its libraries being used with my java application.
I am able to add new files to the database, but when I run an XQuery I get the following output:
error running xquery: declare namespace tr = '[query]org.basex.core.BaseXException: Improper use? Potential bug?

at basex_debug.Corrupt_DB_Test.main(Corrupt_DB_Test.java:23)The query was running fine before so I know there is not a problem with the query, I have only read about the database getting corrupt with BaseX when ran in Server and Client mode.
What may be causing this problem and what are some possible solutions?
