真巧这周在服务器上碰到了这个问题

现象是部分 php 页面突然输出不完整,结构是 1 台服务器跑 nginx 作反代,1 台跑 nginx+php

反代通过 http1.0 协议请求后端时,返回 200 以及不完整页面,
反代通过 http1./1 协议请求后端时,chrome 就报了这个 ERR_SPDY_PROTOCOL_ERROR

突然想起之前 nginx 好像修复过 proxy 相关的 bug,先升级到最新,问题依旧存在

直接看 php 那台服务器,查看 nginx 日志,发现是 fastcgi_temp 在的盘满了

起因是 php 那台服务器跑了个某云服务商自身控制面板就提供有的基础安全检测探针,结果探针有问题,强行更新 apt 某个库,连带更新 mysql,把 mysql 搞挂了,真是日了狗了

守护进程 PM2 日志默认写在系统盘,把系统盘写满了.nginx 也安装在系统盘,然后一些 php 页面返回比较大,需要创建几个 fastcgi_buffer,结果 fastcgi_temp 满了,无法创建 fastcgi_buffer,就只能返回不完整的页面

删了好几个 G 的 pm2 日志,留出空间,搞定...

仅供参考

@shuimugan 啊咧，，我是启用 http2 的情况下，静态文件出现这个毛病，php 我没有通过 https，这个我不清楚是否存在这个问题，我和你的问题可能不相同？

[shuimugan]

@1265578519 #2 是不同的,需要查看 nginx 的 error.log,配合 curl,甚至抓包来排除

[1265578519]

@1265578519 嗯，也是在反代模式下出现，源服务器直接输出没存在问题，硬盘看了并没满。

[1265578519]

@shuimugan 刚看了反代服务端的日志，在前台出现 spdy 错误的时候，输出的内容 errno=[9 Bad file descriptor],socket=20(pool)，

最好能发下 nginx 配置

[0ZXYDDu796nVCFxq]

升级 Nginx，某个版本之前的 http2 模块有 bug
为何还用 1.10.x ？现在 stable 已经是 1.12.2，mainline 已经是 1.13.8 ……

[0ZXYDDu796nVCFxq]

另外配置有问题，为何要对 image/gif 启用 gzip ……

[1265578519]

@gstqc 貌似是长连接时间太长了
反代服务器上游长连接大于源的长连接时间
我调整了加大源服务器的长连接为 120s 后，反代 60s，情况缓解很多，虽然偶尔可能还是会出现。
image，，一些图片内容还是有点压缩率的就开了。

[1265578519]

@gstqc 毕竟出现问题的还有 css js，肯定不是 gzip 毛病了，，，版本升级吗，最新版啊！那些图片是网络中检索的参考。代表很多人都出现这毛病

[1265578519]

问题终结，已解决
