A while ago when I used XML Site Map Module to create the Site Map for my site.
It used all the resources of my website.
Like my server went over the roof and I actually couldn't access the website because server was eventually down.
Then from Drush console I turned off the module and website came back to normal.
I don't know what was the issue but you are more then welcome to visit my website on www.emergingstars.com.
