I noticed some errors coming to the root mail with the subject and the text:
/usr/bin/test -x /usr/local/cpanel/scripts/update_db_cache && /usr/local/cpanel/scripts/update_db_cache
Warning: Using unique option prefix pass instead of password is deprecated and will be removed in a future release. Please use the full name instead.
The problem lies in the file ~ / .my.cnf, that is /root/.my.cnf in my case.
In which the parameter “pass” is obsolete and must be changed to a new “password”.
For example, that’s how it was when the error occurred:
[client] user=root pass=password
Changed to password and the error disappeared:
[client] user=root password=password
