database locked

[Floehe]

When trying to add my first file from a local server source folder, I get the following error:

[2017-12-22 09:03:58,261: ERROR/MainProcess] Task sources.tasks.task_check_interval_source[a2b61d94-0153-4645-9965-d33c2f9dc4df] raised unexpected: OperationalError('database is locked',)

The default database used is SQLite which doesn't support too many open connections at the same time. Working on making MySQL the default database manage.

Why not use Postgres as the default database instead of MySQL?

[Tina Zhou]

I gave Postgres a try but the user creation and authentication stumped me. If you have some experience with Postgres and could provide a step by step for creating users and such I could give it another try.

...I understand the limitations of SQLite but I do not open any connections deliberately. I just added a new new source folder and manually started a check on this folder. Also there are many manage.py tasks running, maybe they all want to access the DB?

this comes approx. 10 times in a ps-ef:
python manage.py celery worker --settings=mayan.settings.production -B -Ofair -l ERROR
