I have spotted a catchable fatal error for Flow and some part of the code relying on AbuseFilter. It is triggered by some unknown async job:

[28-Jan-2014 07:03:06] Catchable fatal error: Argument 1 passed to Flow\SpamFilter\AbuseFilter::construct() must be an instance of User, null given, called in /php-master/extensions/Flow/container.php on line 432 and defined at /php-master/extensions/Flow/includes/SpamFilter/AbuseFilter.php on line 25 Server: deployment-jobrunner08

Another entry a second after is:

[28-Jan-2014 07:03:07] Fatal error: /usr/local/apache/common-local/wikiversions.cdb has no version entry for `[93c62b6b] [no req] Exception from line 544 of /php-master/includes/SiteConfiguration.php: Failed to run getConfiguration.php.

That might be the root cause.
