[basex-talk] Opened by another process

Why would I get a bxerr:BXDB0007 error "Database 'profiles' cannot be updated, as it is opened by another process" when executing these commands from a BaseX client:

open profiles; xquery insert node <profile>abc</profile> into /profiles

Where "profiles" is an existing database, and /profiles an existing root element, and I am quite positive that the database is NOT being used in another process?

When I issue these commands on localhost it is working fine.
