In order to understand what might go wrong, I would once again be
thankful if you could provide us with reproducible steps, or a
self-contained example.

I tried to simulate the repeated insertion in Java, but the attached
Java code does not raise any errors. In the error message you
attached,

org.basex.core.BaseXException: Stopped at ., 1/5847730:
[XPDY0002] TM: no context value bound.

the query parser indicates that you want to address a TM step in your
query – which does not exist if no database is opened, or if no item
is bound to the current context. This is why I asked for the query
that triggered the error (it’s difficult to judge what goes wrong
without having more insight). If your query contains confidential
information, you could open it in the BaseX GUI and jump to the
referenced error position (line 1, column 5847730).

Cheers
Christian
