Hi,
Most of the time, the proxy server reconnects to the 'back-end' server
after an error or loss of connection, but every now and then the
following happens:
Error or connection loss is detected, and the reset sequence is performed.
However, after the new connection to the 'back end' server is
initiated but before it is established, the socket's background
handler is reset and the reestablish of the connection to the 'back
end' server is thus hung forever:

I guess the problem is related to the reset sequence being run from
within SocketDescriptor::tcpReadHandler?
