Hi,

I've quickly tried to reproduce your bug without success. Please, share
you configuration to be sure to do test in the same situation.

It could also be helpful to have a tcpdump for data exchanged between
your client and HAProxy and another one for data exchanged between
HAProxy and your webserver.

If you cannot do a tcpdump, you can use the trace filter by adding the
following line in your frontend/listener section:

filer trace

Then run HAProxy in foreground.

Hi Christopher,
Thanks for your response. I’ve attached the requested configuration and
HAProxy trace logs below (TCPdump appeared to be much noisier). I have an
input file which reproduces the 503 case but not predictably, so I’ve
included one log which generated the correct 401 response from HAProxy and
one which returned a 503 response. The 503 response comes back every time
with larger requests than this. I’ve stripped down the configuration to a
minimum which reproduces the issue.

The behaviour only seems to occur with proxy-protocol enabled
(accept-proxy). I initially tested directly sending requests directly to
HAProxy and that works without the 503 responses. We run this HAProxy
configuration behind Amazon ELB - a TCP load balancer with proxy protocol
enabled, where the issue occurs (and it occurred in my test environment
once proxy protocol was enabled and connections went through the TCP load
balancer).

Thanks,
Jon
