Solving automatic Odoo session disconnections

Many users encountered the same problem: after a period of inactivity, Odoo disconnected them because of its default session behavior. This could interrupt someone in the middle of their work.

Solution: sessions.max_inactivity_seconds

The following key can be added to Odoo's system parameters:

sessions.max_inactivity_seconds

Its value is expressed in seconds. For example, a 12-hour session is:

60 × 60 × 12 = 43,200 seconds

Caution

Do not set the value too low, for example while testing, or you may be disconnected before you can change it again.

If it still happens

Connect to a psql shell on Odoo.sh and run:

UPDATE ir_config_parameter
SET value = '60'
WHERE key = 'sessions.max_inactivity_seconds';

List system parameters

SELECT key, value
FROM ir_config_parameter
ORDER BY create_date DESC;

Reference in the Odoo source code

The behavior is implemented in odoo/http.py, around lines 307 and 449.
