1. What is value of "QA_PERSISTENT_CONN_DB" in qa-config.php on your Q2A root? false or true?
2. Is there detailed information about MySQL connection error in Apache error log on your server?
3. What is value of "max_connections" of your MySQL server.
    Example of console command:
    mysql> show variables like 'max_connections';
