Fatal error: Uncaught PDOException: SQLSTATE[42000] [1203]

Olá, muito boa tarde!

Estou desenvolvendo uma plicação PHP com Composer, na maquina local está tudo funcionando mas quando eu coloco no servidor esta dando o seguinte erro.

Fatal error: Uncaught PDOException: SQLSTATE[42000] [1203] User meucarr2_admin already has more than 'max_user_connections' active connections in

Vou deixar a minha class de conexão, se algum puder me ajudar. Pois não sei o que fazer.
