  "message": "Fixing cpu hog with all upstream servers marked \"down\".\n\nThe following configuration causes nginx to hog cpu due to infinite loop\nin ngx_http_upstream_get_peer():\n\n    upstream backend {\n        server 127.0.0.1:8080 down;\n        server 127.0.0.1:8080 down;\n    }\n\n    server {\n       ...\n       location / {\n           proxy_pass http://backend;\n       }\n    }\n\nMake sure we don\u0027t loop infinitely in ngx_http_upstream_get_peer() but stop\nafter resetting peer weights once.\n\nReturn 0 if we are stuck.  This is guaranteed to work as peer 0 always exists,\nand eventually ngx_http_upstream_get_round_robin_peer() will do the right\nthing falling back to backup servers or returning NGX_BUSY.\n",
