This is what would be expected if the client sent 205512 bytes and then the
server stopped responding for 360 seconds. You didn't say how long it was
from the start of the transfer before this timeout was reached, or how you know
that the response bytes were actually being received. A network sniffer
would tell you where the problem lies.
