[jira] [Commented] (JENA-1586) Fuseki does not close files of dataset when the dataset is removed

-
This fix expels the database for TDB1 and TDB2 databases. That should close
all open files associated with the database.
Tom - if you get a chance to confirm this, please let us know.
Note to anyone else looking at this: On MS Windows, closing the database does
not release the memory mapped files until the process exits. This is a
long-term java issue and marked "won't fix" in the Java Issues tracker.

See [pull request #458|https://github.com/apache/jena/pull/458] which seems to

Hi Andy,
thanks for your reply. I am not using the UI; I make HTTP requests from a PHP
script to the Fuseki server, as described here: [Fuseki HTTP Administration
Protocol|http://jena.apache.org/documentation/fuseki2/fuseki-server-protocol.html].

Hi Tom - are you using UI itself, or the HTTP operations that back the UI to
create/delete datasets? Or some other way?
