当大文件花费超过一分钟时重置

我有一个带有php后端的表单中的多部分文件上传。我已经定好了 max_execution_time 和 max_input_time 在php.ini中设置为180,并在文件上载中确认这些值已设置和设置 TimeOut 在阿帕奇有180个。我也准备好了

RewriteRule .* - [E=noabort:1]
RewriteRule .* - [E=noconntimeout:1]

当我在快速连接上上传一个250MB的文件时,它工作得很好。当我使用较慢的连接或网络链接调节器来人为地降低速度时,相同的文件会超时,在chrome上也会出现 net::ERR_CONNECTION_RESET 1分钟(5秒)后可靠。我也尝试过其他浏览器,结果相同,只是错误信息不同。

在任何日志中都没有错误的迹象,我已经试过了 http 和 https .

什么会导致1分钟后重置上载连接?

编辑

我现在还尝试了一个简单的上传表单,它绕过了我正在使用的任何框架,仍然在1分钟内超时。

我还制作了一个睡眠脚本,在2.5分钟后超时,这很有效,页面加载大约需要2.5分钟,所以我看不出它是如何与浏览器或标题相关的。

我还使用了一个具有更多ram的服务器来确保它与此无关。我已经在3个不同的服务器上测试了不同的规格,但都来自同一个centos 7的基础。

我现在也升级到了php 7.2,并再次更新了相关字段,没有任何问题。

编辑2 这个独立实例的技术堆栈是

• Apache 2.4.6
• php 5.6/7.2(两者都试过了),有opcache
• 用于会话信息和密钥/值存储的Redis 3.2.6(Elasticache)
• PostgreSQL 10.2(无线电数据系统)

我的技术堆栈中的其他所有内容都已从该测试区域中删除,以尝试隔离问题。efs在系统上,但在我最孤立的测试中,它只是使用ebs。
