I came across this uncaught exception when logging into torn.
Happy to contribute to the fix but I have no idea if it's opensource or not.
Fatal error: Uncaught exception 'MongoCursorTimeoutException' with message 'mongodb-a.torn.com:27017: Read timed out after reading 0 bytes, waited for 2.000000 seconds' in /torncity/html/includes/authenticate/TCAuthenticate.php:344 Stack trace: #0 /torncity/html/includes/authenticate/TCAuthenticate.php(344): MongoCollection->insert(Array) #1 /torncity/html/includes/authenticate/TCAuthenticate.php(8): TCAuthenticate->preAuthenticateCheck() #2 /torncity/html/authenticate.php(12): TCAuthenticate->__construct() #3 {main} thrown in /torncity/html/includes/authenticate/TCAuthenticate.php on line 344
