You'll also see that curl leaves the connection open after its request:

... but when it later wants to re-use the connection it left open:

... the connection seems to be non-functional and it needs to create a new
one. The check there checks if the socket is readable and if it is, it is a
bad situation and it is therefore considered to be a dead connection. See
lib/url.c:SocketIsDead() called from ConnectionExists().

Then please point out the error in curl. I'm not aware of any particular error
in this part of the code in any recent curl version.
