Forum:"Cannot contact the database server: No such file or directory"

We're seeing this error on many pages on both allthetropes and poserdazfreebies (including the main page on allthetropes), and any time when anybody tries to upload a file to poserdazfreebies:

Sorry! This site is experiencing technical difficulties. Try waiting a few minutes and reloading. (Cannot contact the database server: No such file or directory)

The message is sometimes repeated.

It seemed to start about the time HHVM was rolled out, but I don't know whether the two are related. Do we know when this will be resolved?

 * I'm getting similar pages on RedSec. Lieutenant S., Geschichtsmeister des Lexipedium (talk) 01:54, 22 September 2014 (BST)
 * The cause is unknown but is unrelated to HHVM. If you switch to HHVM the problem is actually solved so please do that. I've been aware of this issue for 2/3 days now but as no logs are being generated for the error at all besides 'no such file or directory' I am unable to debug it.

 * Partial solution only - I still can't upload images. (See https://poserdazfreebies.orain.org/wiki/File:Imperial_Shuttle_%28Lambda_Class%29.png for an example) --Robkelk (talk) 01:07, 23 September 2014 (BST)
