I don't know whats causing it as these are error messages appearing on my server. Hopefully this is enough information to diagnose the problem, if it is even a problem. It may simply just be a warning or informational message.

It's just a warning nothing to worry about, we have an issue already to reduce the spam.
But if this warning appears and the worker isn't working you might need this log.
