     [EAGAIN]           The socket is marked non-blocking and the requested
                        operation would block.

It's just a socket message saying it can't write the data it wants to 
write into that particular TCP session... This COULD potentially 
indicate a problem, such as congestion or errors, but it can also just 
be a quick dump of data filling up the socket buffer before the other 
side can read it. 99% odds are this is cosmetic. :)
