We have a big problem with the server. 
Odoo stops abruptly without any error and in the console you can see "killed". Does anyone have a solution, I am on Odoo14. I thank you in advance 
Odoo is the world's easiest all-in-one management software.
 It includes hundreds of business apps:
- CRM
- e-Commerce
- 会計
- 在庫
- PoS
- プロジェクト
- MRP
 
                        
Try restarting your database, the comand has to be like this --> systemctl restart postgresql
