Hi,

We have been getting unusual situations where the several users have been logged off from the system automatically while leaving the screen unattended. Then on the server we are getting these errors in application-server.log:

The issue seems to be appearing for both single sign on (Active Directory users), and users using username & password. Can anyone shed some lights of what is actually causing this?

Is this session expiry period defined in custom.properties through this property?

That setting is more about after how long the warning will be displayed. The session timeout feature itself involves two aspects: this warning setting and the timeout in web.xml as explained here forum.appian.com/.../Post-Install_Configurations
