Hello Willy,
It works perfect! Problem solved :) >From my side, yesterday afternoon I was walking along the commits to reach >when was the change. I finished in the same commit "MEDIUM: connection: make >conn_sock_shutw() aware of lingering", and the workaround that I found was >using "option nolinger". Coincidentally, when I was going to write the email, >your answer arrived with the right fix. The doubt that I have now is related with the trace line "-1 ENOTCONN (Transport endpoint is not connected)" and the relationship with the issue... It still happend, but the problem is solved, therefore it hasn't any link between each one. I found that this behaviour was introduced since the commit "3256073976d4f43e12e7ff97d243fdb8eb56165a - MEDIUM: stream: do not forcefully close the client connection anymore", but I can't reproduce it if I make the test sending the request (a simple curl) from outside the server network using a vpn link. Due that I can't see any other issue, does it fit inside the expected behaviour? Thanks for your time Willy and Christopher. ________________________________ De: Willy Tarreau <[email protected]> Enviado: viernes, 22 de diciembre de 2017 18:57 Para: Ricardo Fraile Cc: [email protected] Asunto: Re: Issue after upgrade from 1.7 to 1.8 related with active sessions Hi Ricardo, On Fri, Dec 22, 2017 at 12:37:42PM +0100, Ricardo Fraile wrote: > Continuing with the investigation, I changed the listen only to this: > > listen proxy-test-tcp > bind *:81 > option tcplog > server test1 192.168.1.101:80 > > > And the difference between 1.7 and 1.8 tracing the process who receive > only 1 request is that the shutdown of the socket who receives the > request fails with an ENOTCONN.

I've just fixed it now with the attached patch. Feel free to retest it, but I'm confident I can issue 1.8.2 now. Many thanks for your very detailed report! Willy
