The log snippet is not giving us much to work with. It looks like WeeWX is trying to load MQTTSubscribe. Is this happening when WeeWX is started? Did WeeWX crash and is restarting? What happens after this? Does WeeWX exit? Since a thread cannot be started, it seems like a system resource issue... What else is running on your Pi? How does the memory usage look,? etc....
