I've just started to get this error, it's not spat this error out before, It's all updated etc.

UPDATE: Contacted my server hosting, I've been told they have a error on there side causing servers to show [Server] WARN No space left on device. This could be causing the error, I'll update this post when I receive further updates.
Thanks
