hi @liuquanlong2017

you might want to check this forum post, as it contains useful links regarding the database locked error that you are intermittently experiencing

Grafana SQLite database locked

Hi @schachre1998, Please check this GitHub issue which shows a possible workaround. Also, SQLite has some limitations (see Notes section) and therefore is not recommended for use in a production environment. I hope this helps.
