Post the output of "haproxy -vv". Also you did not post the output of
the debug logs.

Hi Ricardo,

Can you post the full configuration? The part about timeouts
is important in this case.

Also, please specify what release you are using.

That sounds like simple packet loss issue to me.

Can you tcpdump frontend and backend traffic of such a broken session?
Could you start haproxy in debug mode, reproduce the issue and post the
log?
