Using the "httpd" Chef cookbook, httpd is killed after every request - apache

Question

I'm provisioning a vagrant vm using chef_solo, using bento/centos7.2. I'm installing httpd through the httpd cookbook with the following code.
# Install Apache and starts it
httpd_service 'mine' do
mpm 'prefork'
action [:create, :start]
listen_ports ['80', '443']
run_user node['webserver']['run_user'] # the value is 'vagrant'
end
# Add the site configuration
httpd_config 'mine' do
instance 'mine'
source 'mine.conf.erb'
notifies :restart, 'httpd_service[mine]'
end
# Create document rood directory
directory "#{node['webserver']['document_root']}" do
recursive true
end
# Homepage
template "#{node['webserver']['document_root']}/index.php" do
source 'index.php.erb'
mode '0644'
owner node['webserver']['user']
group node['webserver']['group']
action :create_if_missing
end
# Install the mod_php Apache module.
httpd_module 'php' do
instance 'mine'
end
# Install memcached
package 'memcached'
# Install php-pecl-memcache
package 'php-pecl-memcache' do
action :install
notifies :restart, 'httpd_service[mine]'
end
# Install php-pecl-memcached
package 'php-pecl-memcached' do
action :install
notifies :restart, 'httpd_service[mine]'
end
# Install php-mysql
package 'php-mysql' do
action :install
notifies :restart, 'httpd_service[mine]'
end
# Install php-pdo
package 'php-pdo' do
action :install
notifies :restart, 'httpd_service[mine]'
end
# Install php-intl
package 'php-intl' do
action :install
notifies :restart, 'httpd_service[mine]'
end
# Install php-mssql
package 'php-mssql' do
action :install
notifies :restart, 'httpd_service[mine]'
end
Funny thing is, When I run kitchen converge everything is good and httpd works perfectly (InSpec test pass, and I manually verify with kitchen login).
But when I run on vagrant, it is killed from the very beginning, and it dies after each request. I don't know why, nor I know if there is any log I can read to debug this behavior. Any ideas?
UDPATE:
This is the log found in /var/log/httpd-mine/error_log
This is the log in sudo journalctl
