Hi Friends,
We upgraded to HAProxy 1.8.14 from 1.7.11 and saw an uptick in the number of
browser related 503 requests with termination reason CC. TC, TR and TW are
consistent across these requests and are -1,-1,0 respectively, these requests
are proxied to nginx, the only thing that has changed so far in our setup is
upgrading from 1.7.11 to 1.8.14. Find below an example log entry:
{"proxy_server_name":"http-in","proxy_tq":"826","proxy_tw":"0","proxy_tc":"-1","proxy_tr":"-1","proxy_tt":"826","http_status_code":"503","http_bytes_read":"0","http_captured_request_cookie":"-","http_captured_response_cookie":"-","proxy_termination_state":"CC--","proxy_active_connections":"131","proxy_frontend_connections":"104","proxy_backend_connections":"27","proxy_server_connections":"27","proxy_retries":"0","proxy_server_queue":"0","proxy_backend_queue":"0","http_method":"GET","http_request_url":"/favicon.ico","ssl_version":"TLSv1.2","ssl_cipher":"ECDHE-RSA-AES128-GCM-SHA256"}
I can share our config if required, I am not including it in this email
because of it's size and hope we can narrow down to specifics that will be
easy to share.
Do folks know if there any known things that could have changed between 1.7
and 1.8 to have introduced this uptick?
Thanks!
