Hi, I'm getting weird 503 error on varnish.
On page with ESI ( not on every page of my website ) i got Error 503 Backend fetch failed. On varnish log i can saw FetchError http read error: overflow : * << BeReq >> 9 - Begin bereq 8 fetch - Timestamp Start: 1476370852.736703 0.000000 0.000000 - BereqMethod GET - BereqURL /pageXXX.html - BereqProtocol HTTP/1.1 - BereqHeader Host: www.websiteXXXX.com - BereqHeader User-Agent: Mozilla/5.0 (X11; Ubuntu; Linux x86_64; rv:47.0) Gecko/20100101 Firefox/47.0 - BereqHeader Accept: text/html,application/xhtml+xml,application/xml;q=0.9,*/*;q=0.8 - BereqHeader Accept-Language: fr-FR - BereqHeader Cookie: mage-translation-storage=%7B%7D; mage-translation-file-version=%7B%7D; mage-cache-storage=%7B%7D; mage-cache-storage-section-invalidation=%7B%7D; mage-cache-sessid=true; X-Magento-Vary=f970ba1c8edf4251be121a7535f2ce003b791953; form_key=lV5GbPY6uP - BereqHeader X-Forwarded-For: 80.74.72.196 - BereqHeader Accept-Encoding: gzip - BereqHeader X-Varnish: 9 - VCL_call BACKEND_FETCH - VCL_return fetch - BackendOpen 53 default(127.0.0.1,,81) 127.0.0.1 59720 - Backend 53 default default(127.0.0.1,,81) - Timestamp Bereq: 1476370852.736959 0.000256 0.000256 - FetchError http read error: overflow - BackendClose 53 default(127.0.0.1,,81) - Timestamp Beresp: 1476370865.707061 12.970358 12.970102 - Timestamp Error: 1476370865.707072 12.970368 0.000011 - BerespProtocol HTTP/1.1 - BerespStatus 503 - BerespReason Service Unavailable - BerespReason Backend fetch failed - BerespHeader Date: Thu, 13 Oct 2016 15:01:05 GMT - BerespHeader Server: Varnish - VCL_call BACKEND_ERROR - BerespHeader Content-Type: text/html; charset=utf-8 - BerespHeader Retry-After: 5 - VCL_return deliver - Storage malloc Transient - ObjProtocol HTTP/1.1 - ObjStatus 503 - ObjReason Backend fetch failed - ObjHeader Date: Thu, 13 Oct 2016 15:01:05 GMT - ObjHeader Server: Varnish - ObjHeader Content-Type: text/html; charset=utf-8 - ObjHeader Retry-After: 5 - Length 278 - BereqAcct 611 0 611 7767 0 7767 - End My website is a magento 2. So I suppose this is my issue : http://devdocs.magento.com/guides/v2.0/config-guide/varnish/tshoot-varnish-503.html But even with this option http_resp_hdr_len it doesn't work... Can anyone know how to debug this ?
