i had really series problem with my vps.
my websites goes down on heavy-stress time. the vps goes really slow and i get database error connection.
i tired to change handler to suphp or ... but no luck. reinstall apache2.4 reinstall and reconfigure apache change php version to 5.6 or 7.3 its same. also with 10gb swap memory size no luck. its eating all.
on error log i just got this error when website goes down
PHP Warning: mysqli_query(): (00000/0): in /wp-includes/wp-db.php on line 2007 PHP Warning: Empty row packet body in /wp-includes/wp-db.php on line 2007
no luck at all . its goes down on heavy stress. i have no problem in this two years. its appear from 5days ago until yet.
