Hello Community, 

This morning my odoo-server crashed, the last messages I got were: 'Access Denied by ACLs for operation: read, uid: 4 (where uid 4= public user) (full message below)

This is an installation that ran smoothly for the last 2 years. No changes where made that can justify this error. 

The error message pops-up for different models trough the logs in the last hours and at the moment of crashing multiple times in a row. 

I know what the error means (no acces to a certain object for the specific user) but why is it showing now and why is the server crashing because of this?

Thank you very much for your help!

Greetings,
