Kako se proverava

Run SELECT VARIABLE_NAME, VARIABLE_VALUE FROM performance_schema.global_variables WHERE VARIABLE_NAME LIKE 'max_%connections'; (max_user_connections 0 = no limit) and SELECT user, host, max_user_connections FROM mysql.user WHERE user NOT LIKE 'mysql.%' AND user <> 'root'; (0 = global value applies). No server or per-user limit is a fail.

Set max_connections and max_user_connections under [mysqld] (SET GLOBAL to apply now) and per account with ALTER USER '<user>'@'<host>' WITH MAX_USER_CONNECTIONS <n>;
