Transfer Error w/ Log

Hey guys- new to the forums for a problem I've been having for a little while now and I'm not sure what it is.

I'm trying to upload this 3GB file onto my host that holds 10GB total and I know that there is space and I just can't seem to get this file to host. I used to use Filezilla and it was giving me crap with this so I switched to SmartFTP (which I love a lot better now, anyway) but its still giving me troubles. Does anyone know what the Log is telling me?

Theres a whole lot more to the log but I'm pretty sure this is the only relevent section.

Any help would be great. Thanks!
