We have an apache server stopping serving requests constantly due to the following error:
(70007)The timeout specified has expired: [client xxx.xxx.xxx.xxx:33740] AH01075: Error dispatching request to : (polling), referer: https://www.google.com/
[proxy_fcgi:error] [pid 12363:tid 139906999342848] [client xxx.xxx.xxx.xxx:6318] AH01067: Failed to read FastCGI header
It seems no matter what we do, this keeps happening, I have tried setting the timeout in the php.conf:
#
# Cause the PHP interpreter to handle files with a .php extension.
#
RequestReadTimeout header=180 body=180
<FilesMatch \.php$>
SetHandler "proxy:unix:/var/run/php-fpm/php5-fpm.sock|fcgi://127.0.0.1 timeout=1800 connectiontimeout=1800"
</FilesMatch>
<Proxy "unix:/var/run/php-fpm/php5-fpm.sock|fcgi://127.0.0.1" timeout=1800 connectiontimeout=1800>
ProxySet timeout=1800 connectiontimeout=1800
</Proxy>
<Proxy "fcgi://127.0.0.1">
ProxySet timeout=1800 connectiontimeout=1800
</Proxy>
#<FilesMatch \.php$>
# SetHandler application/x-httpd-php
#</FilesMatch>
#
# Allow php to handle Multiviews
#
AddType text/html .php
#
# Add index.php to the list of files that will be served as directory
# indexes.
#
DirectoryIndex index.php
#
# Uncomment the following lines to allow PHP to pretty-print .phps
# files as PHP source code:
#
#<FilesMatch \.phps$>
# SetHandler application/x-httpd-php-source
#</FilesMatch>

The timeout is set to 180 for Apache. php.ini has default_socket_timeout = 180

I read an article about a patch but it did not apply to our version of Apache in respect to the timeout issue.
MySQL and Memcached are running on other servers.
Any ideas?
