I have the follow unresolved problem regarding PHP and Apache. I have a long running script that ALWAYS return 504 Gateway Timeout after 30 seconds running. However, if I check in /server-process, I can see that the request is still going on. Before being suggested, I'm not expecting it to be a cron job as this long process should finish just under a minute and for current situation, I needed it to run inside browser. Here's what I've set the server:

/etc/apache2/apache2.conf
- Timeout 600

/etc/php/7.0/apache2/php.ini
- max_execution_time = 300
- max_input_time = 300

Here's my server info:

root@izzystorage-core:~# lsb_release -r
Release:        16.04

root@izzystorage-core:~# apache2 -v
Server version: Apache/2.4.18 (Ubuntu)
Server built:   2017-09-18T15:09:02

root@izzystorage-core:~# php -v

Do you guys have any Idea what's going on with my server?

edit

1. I don't have mod_proxy
2. This is only one server without load balancer in between

Out of curiosity, I wanted to know, how Wordpress.com scale their architecture, specifically:

1. how they handle sub-domains.

   I believe they have millions of subdomains.CMIIW. How do they scale their DNS to handle it?

2. They also support custom domains.

   How do they handle the translation and also, how do they scale the requests?

note, I choose the wordpress tag, because I'm not allowed yet to create wordpress.com tag.

As stated on question's title, I ran into situations and I need to check something. Here's the condition. When I do top, I see mysql process with ID, say 1234. But, when I execute show processlist from mysql, I don't see process ID 1234. My question is, can I connect those ID from top with ID from mysql. If so, how do I do that?

I hope the question is clear.

So, I'm using my ssh tunneling to download some content which is blocked by my office. But, I don't want the admin to notice it, therefore I want to limit the connection to, eg: 20KB/s.

How can I do that? FYI: -I'm using DownThemAll to download the content. -I'm using ubuntu 9.04
