We've had odoo v11 for about a year now and it worked fine. Now all of a sudden we get HTTP500 error on a daily basis:
Internal Server Error
The server encountered an internal error and was unable to complete your request. Either the server is overloaded or there is an error in the application.
Apparently the posgres service falls, and must be restarted from ubuntu using:systemctl status odoo.service
How can i debug this?
