Hi Sebastián,
Can the error be reproduced with BaseX 9.x? Did you access the affected databases outside the client/server context (e.g. from the GUI or other BaseX instances, while your server was running)? If not, you could check the database logs and find out which actions were performed before the first error occurred.
Best, Christian

Hello,
I have several databases running and when I try to query one of them I'm getting the attached exception trace. Any ideas?
