That's a debug output I put there once to aid me debugging a transfer case I
had problems with and I then left it there. If is only present in debug builds
and basically if you need to ask about it, the message is not for you...

It just explains that the transfer is not deemed complete yet. You need to
look at protocol and TCP details to see what's going on - but it sounds like
you're experiencing some bug somewhere if it uses that much CPU.
