Flow is VERY noisy in the logs atm

With a quick glance over the last hour (July 1st, 12:30-1:40 pacific time), the majority of these are still showing up in the fatal log.

This may be fixed with 1.24wmf12...

Flow does not appear to be spamming the logs at the moment, this specific error was likely fixed awhile ago as reedy mentioned.
