 Priority:  normal        |  Milestone:  Awaiting Review

--------------------------+-----------------------------
 Current behavior:
 When WordPress web site was under high concurrency access, the database
 connections may reach the limitation of the system resource. WordPress was
 still returning 200 of HTTP response code when database connection error
 happens.

 The page with error information as:
 Error establishing a database connection
 This either means that the username and password information in your wp-
 config.php file is incorrect or we can't contact the database server at
 dbhost. This could mean your host's database server is down.

 Expected behavior: Returns HTTP code with 500 or other error codes to
 indicate error happens, when showing error pages.
