Segmode错误4在libmysqlclient.so中

好，所以这些segfaults对应于我的客户网站中的错误。 对于这些segfaults：

 Sep 23 21:39:07 server kernel: [164772.739464] php5-fpm[10375]: segfault at 7f9ade4be018 ip 00007f9ae4026772 sp 00007ffd69b4fad0 error 4 in libmysqlclient.so.18.0.0[7f9ae3ff9000+2f1000] Sep 23 22:08:47 server kernel: [166554.093566] php5-fpm[12582]: segfault at 7f9ade5d9018 ip 00007f9ae4026772 sp 00007ffd69b4fad0 error 4 in libmysqlclient.so.18.0.0[7f9ae3ff9000+2f1000] Sep 23 22:09:17 server kernel: [166584.252833] php5-fpm[31132]: segfault at 7f9ade669018 ip 00007f9ae4026772 sp 00007ffd69b4fad0 error 4 in libmysqlclient.so.18.0.0[7f9ae3ff9000+2f1000] Sep 23 22:10:30 server kernel: [166656.875041] php5-fpm[24992]: segfault at 7f9ade6e9018 ip 00007f9ae4026772 sp 00007ffd69b4fad0 error 4 in libmysqlclient.so.18.0.0[7f9ae3ff9000+2f1000] Sep 23 22:39:19 server kernel: [168387.935728] php5-fpm[27380]: segfault at 7f9ade654018 ip 00007f9ae4026772 sp 00007ffd69b4fad0 error 4 in libmysqlclient.so.18.0.0[7f9ae3ff9000+2f1000] Sep 23 22:48:55 server kernel: [168963.750727] php5-fpm[6309]: segfault at 7f9ade371018 ip 00007f9ae4026772 sp 00007ffd69b4fad0 error 4 in libmysqlclient.so.18.0.0[7f9ae3ff9000+2f1000] Sep 23 22:49:33 server kernel: [169001.961155] php5-fpm[15416]: segfault at 7f9ade40f018 ip 00007f9ae4026772 sp 00007ffd69b4fad0 error 4 in libmysqlclient.so.18.0.0[7f9ae3ff9000+2f1000] Sep 23 23:04:22 server kernel: [169892.025852] php5-fpm[5763]: segfault at 7f9ade422018 ip 00007f9ae4026772 sp 00007ffd69b4fad0 error 4 in libmysqlclient.so.18.0.0[7f9ae3ff9000+2f1000] Sep 23 23:04:50 server kernel: [169919.986130] php5-fpm[16016]: segfault at 7f9ade5cf018 ip 00007f9ae4026772 sp 00007ffd69b4fad0 error 4 in libmysqlclient.so.18.0.0[7f9ae3ff9000+2f1000] Sep 23 23:09:11 server kernel: [170181.423023] php5-fpm[5129]: segfault at 7f9ade6cc018 ip 00007f9ae4026772 sp 00007ffd69b4fad0 error 4 in libmysqlclient.so.18.0.0[7f9ae3ff9000+2f1000] 

我得到了我的nginx日志错误，正是在同一时间，所以不是巧合的错误：

 2017/09/23 21:39:07 [error] 808#0: *7346034 recv() failed (104: Connection reset by peer) while reading response header from upstream, client: 1.1.1.1, server: example.com, request: "GET /page/a-page HTTP/1.1", upstream: "fastcgi://127.0.0.1:9000", host: "example.com", referrer: "https://example.com/page/another-page" 2017/09/23 22:08:47 [error] 808#0: *7443193 recv() failed (104: Connection reset by peer) while reading response header from upstream, client: 1.1.1.1, server: example.com, request: "GET /engine/search?q=query", upstream: "fastcgi://127.0.0.1:9000", host: "example.com" 2017/09/23 22:09:17 [error] 808#0: *7450102 recv() failed (104: Connection reset by peer) while reading response header from upstream, client: 1.1.1.1, server: example.com, request: "GET / HTTP/1.1", upstream: "fastcgi://127.0.0.1:9000", host: "example.com" 2017/09/23 22:10:30 [error] 808#0: *7450989 recv() failed (104: Connection reset by peer) while reading response header from upstream, client: 1.1.1.1, server: example.com, request: "GET /page/a-page HTTP/1.1", upstream: "fastcgi://127.0.0.1:9000", host: "example.com", referrer: "https://example.com/page/another-page" 2017/09/23 22:39:19 [error] 808#0: *7553713 recv() failed (104: Connection reset by peer) while reading response header from upstream, client: 21.1.1.1, server: example.com, request: "GET /page/a-page HTTP/1.1", upstream: "fastcgi://127.0.0.1:9000", host: "example.com", referrer: "https://example.com/engine/search?q=query" 2017/09/23 22:48:55 [error] 7800#0: *7578116 recv() failed (104: Connection reset by peer) while reading response header from upstream, client: 1.1.1.1, server: example.com, request: "GET /engine/search?q=query HTTP/1.1", upstream: "fastcgi://127.0.0.1:9000", host: "example.com" 2017/09/23 22:49:33 [error] 7800#0: *7582962 recv() failed (104: Connection reset by peer) while reading response header from upstream, client: 1.1.1.1, server: example.com, request: "GET /page/a-page HTTP/1.1", upstream: "fastcgi://127.0.0.1:9000", host: "example.com" 2017/09/23 23:04:22 [error] 7800#0: *7639594 recv() failed (104: Connection reset by peer) while reading response header from upstream, client: 1.1.1.1, server: example.com, request: "GET /page/a-page HTTP/1.1", upstream: "fastcgi://127.0.0.1:9000", host: "example.com" 2017/09/23 23:04:50 [error] 7800#0: *7636486 recv() failed (104: Connection reset by peer) while reading response header from upstream, client: 1.1.1.1, server: example.com, request: "GET /page/a-page HTTP/1.1", upstream: "fastcgi://127.0.0.1:9000", host: "example.com", referrer: "https://example.com/engine/search?q=query" 2017/09/23 23:09:11 [error] 7800#0: *7654327 recv() failed (104: Connection reset by peer) while reading response header from upstream, client: 1.1.1.1, server: example.com, request: "GET /engine/search?q=query3 HTTP/1.1", upstream: "fastcgi://127.0.0.1:9000", host: "example.com" 

所以这是我的这个网站的nginx虚拟主机：

 server { listen 80; listen 443; server_name example.com; if ($http_x_forwarded_proto = "http") { return 301 https://$server_name$request_uri; } ssl on; ssl_certificate /etc/nginx/cloudflare_cert/fullchain.pem; ssl_certificate_key /etc/nginx/cloudflare_cert/privkey.pem; include /etc/nginx/conf.d/cloudflare; root /var/www/website; index index.php; location / { # main rewrite rule try_files $uri $uri/ /index.php?/$request_uri; proxy_http_version 1.1; proxy_set_header Upgrade $http_upgrade; proxy_set_header Connection "upgrade"; proxy_set_header Host $http_host; proxy_set_header X-Real-IP $remote_addr; proxy_set_header X-Forward-For $proxy_add_x_forwarded_for; proxy_set_header X-Forward-Proto http; proxy_set_header X-Nginx-Proxy true; } # php parsing location ~ \.php$ { include fastcgi_params; fastcgi_pass 127.0.0.1:9000; fastcgi_index index.php; fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name; } error_log /var/log/nginx/example_error.log; access_log /var/log/nginx/example_access.log; } server { listen 80; listen 443; server_name www.example.com; return 301 https://example.com$request_uri; } 

所以这是一个客户端问题。 现在我必须了解recv() failed (104: Connection reset by peer) while reading response header from upstream何时recv() failed (104: Connection reset by peer) while reading response header from upstream以及如何解决这个问题。
