Hi, I am setting up two Odoo server instances in AWS and access to a single database in a Postgresql RDB. Hope it could be a high availability framework and even apply autoscale in AWS later. I use same Odoo configuration file in the two Odoo instances (i.e. same access db path, port, db_username, db_password).  But I find its seems a 2nd Odoo instance has problem of displaying layouts in browser after logging the database (I could login via /web/database/manager from both Odoo instances).

Anyone know special care to Odoo or Postgresql DB configurations or else?
