I don't know about this one

 but when it comes to this one, I would say that the main reason
why a read() keeps hanging on a TCP socket is that the client or peer
has not shut down the connection, that is, the client or peer has not
performed a shutdown(), close() or exit().

Of course, you could argue that mod_ssl should have implemented a
timeout for conditions like that.

Maybe there is some kind of protocol problem here, in that mod_ssl is
still expecting data, while the client thinks there is no more data
to send, or maybe the client too is hanging in a read().

This url sounds like the problem I'm having.

Any solution to the above?
