We have a webpage with ~20000 pageviews/day. This page usually uses ~15-20 php5-fpm children, but sometimes it reaches the maximum number of children and the site will be unavailable about ~15 mins. (150) It doesn't happen necessarily in peak time. And php5-fpm/nginx restart doesn't help, when I restart the php5-fpm, It instantly reaches the max number of children.

Here is my config files: https://drive.google.com/folderview?id=0BxIEpo_vWLGZeFVZUXBMRTA3QXc&usp=sharing

I don't know how can I find what causes it. What should I do for fix this issue?

I have a problem with nginx/pagespeed module. The images cache-time is default 5 mins on first pageload.

First time: enter image description here

Second time: enter image description here

There are in my nginx.conf:

##
# PageSpeed
##
pagespeed on;
pagespeed FileCachePath /var/ngx_pagespeed_cache;
pagespeed Domain https://example.com;
pagespeed Domain *.example.com;
pagespeed MapOriginDomain "http://localhost" "https://example.com";


pagespeed LoadFromFile "https://example.com" "/usr/share/nginx/www/";
pagespeed LoadFromFileRuleMatch Disallow \.php$;

pagespeed XHeaderValue "Powered By ngx_pagespeed";
pagespeed ListOutstandingUrlsOnError on;
pagespeed EnableFilters extend_cache;

# image related
pagespeed EnableFilters rewrite_images;
pagespeed EnableFilters convert_gif_to_png;
pagespeed EnableFilters convert_jpeg_to_progressive;
pagespeed EnableFilters strip_image_color_profile;
pagespeed EnableFilters strip_image_meta_data;
pagespeed EnableFilters jpeg_subsampling;
pagespeed EnableFilters lazyload_images;

# code related
pagespeed EnableFilters collapse_whitespace;

# DNS related
pagespeed EnableFilters insert_dns_prefetch;

# JS related
pagespeed UseExperimentalJsMinifier on;
pagespeed EnableFilters rewrite_javascript;
pagespeed EnableFilters combine_javascript;

# css related
pagespeed EnableFilters rewrite_css;
pagespeed EnableFilters prioritize_critical_css;
pagespeed EnableFilters combine_css;
pagespeed EnableFilters outline_css;
pagespeed EnableFilters flatten_css_imports;

How can I modify the default 5 mins cache-time? How can I pass the images on first pageload via pagespeed module?

It didn't help:

    location ~* \.(jpg|jpeg|gif|png|ico|cur|gz|svg|svgz|mp4|ogg|ogv|webm|htc)$ {
        expires 1y;
        access_log off;
        add_header Cache-Control "public";
        try_files $uri =404;
    }

    location ~* \.(pdf|js|css|swf)$ {
        expires 1M;
        access_log off;
        add_header Cache-Control "public";
        try_files $uri =404;
    }

Here is my result of service nginx status command. (Debian 8 64bit)

Loaded: loaded (/lib/systemd/system/nginx.service; enabled)

       └─31856 nginx: worker process

I don't really understand what Process: 31845 ExecStop=/sbin/start-stop-daemon --quiet --stop --retry QUIT/5 --pidfile /run/nginx.pid (code=exited, status=2) means and why I get status code 2. Anyway It seems that nginx is working properly.

What should I do to resolve this message?
