Hello, few days ago i did upgrade from debian 10 to 11. Looks like most things works fine (not sure about fail2ban, send emails, rkhunter...), but in sys log i can see every 5 minutes, when ispconfig is done this message Code: Aug 19 13:50:07 mariadbd[795]: 2021-08-19 13:50:07 3947 [Warning] Aborted connection 3947 to db: 'unconnected' user: 'unauthenticated' host: 'localhost' (This connection closed normally without authentication) Any idea why? Maybe limits? Because my db working fine, no errors in mysql log and other logs nothing about db.
