I have a client who is getting the error:
Fatal error: Uncaught exception 'PDOException' with message 'SQLSTATE[HY000] [2003] Can't connect to MySQL server on 'XXX.XXX.XXX.XXX' (4)' in /htdocs/library/rb.php:65
The really odd thing here is that it's not consistent... I can't even reproduce the error. Hitting refresh will, apparently, always bring requested page up without problems.
What could be causing this? Any ideas?
The problem was that the windows server does not have PDO mysql drivers installed.
