I have some warnings in my database log:
[Warning] Aborted connection 155 to db: ‘db’ user: ‘*user’ host: ‘localhost’ (Got an error reading communication packets)
It occurs in every 3 min. I have the latest stable z-push, PHP 7.2.6-1, MariaDB 10.3.7 and apache webserver on my Ubuntu 18.04 LTS server with 32GB ram. The backend is IMAPBackend, and IPC-memcached is installed.
Has anyone warning like this?
