closed <a href="https://sqlite.org/wal.html">https://sqlite.org/wal.html</a>. There are other ways to invoke checkpoint, but if you have for example opened some layer from the database into QGIS map the checkpoint cannot write the changes into the database
because QGIS and SQLite must have a common understanding about what was the contents of the layer when QGIS opened it. Closing the connections when you do not need them anymore should help with the max 64 problem as well.<o:p></o:p></span></p>
