SQLSTATE[HY000] [1040] Too many connections
On a shared hosting, "unlimited" means other users are unrestricted with their resource using. Means they can eat up whole pool, while your consumption remains modest This is a limit of database's configuration. If you have permission to edit the configuration file of your database service, you can change max_connections value. You can try running this SQL query (take care about this value!) SET GLOBAL max_connections = 512; and this to get current value of all variables: SHOW VARIABLES; or (for specific variable): SHOW GLOBAL VARIABLES LIKE '%max_connections%'
