cron.php it is launched from the www-data user as recommended every 5 minutes and every 5 minutes the following message appears in dead.letter:

Doctrine\DBAL\Exception: Failed to connect to the database: An exception occurred in the driver: could not find driver in /var/www/cloud/lib/private/DB/Connection.php:140 Stack trace:

well, then the call stack.

max number of users in MySQL = 151, per day Max_used_connections = 18

At the same time, the site is working NORMALLY, the Win application is NORMAL, the Android application is NORMAL.
