What client are you using? Seems like a low level stack error where a junk data is being processed as a message. Possible a memory fault.

That’s really large buffer for a message: comes to 512 MB! I doubt that it is right.
Besides, the original number reported (301991168) corresponds to 0x12000500. That “looks” suspicious for it to be the intended message size – besides being big, it can be two 16-bit values rather than a single 32-bit. It looks more like that you are connecting to a port that runs a different protocol, or that the server side returns junk.
