Well, about the error, I can say that the network was ok (I had another database 
replicating) and my tables wasn't corrupted (myisamchk / check table / selects) it was 
something really weird.

I'm fighting with my MASTER problems (table corruption).

HI!

The above error message looks like you have hit a very hard error in
network protocol. 

It could be a cause for table corruption, although we would prefer to
see a full repeatable test case .

But for the start, you could check that you have no errors in your LAN
network functioning.
