Enfold may be crashing my server

I am currently having a problem with Enfold (and a child theme set up by a graphic design company). Activating the Enfold theme is causing mysql to start taking forever to look up anything, causing lots of timeouts and periodically even preventing httpd from finding the associated database. When this happens, running commands on the server becomes intolerably slow (like, enter a command, wait fifteen minutes or so, come back to see results). Putty periodically cannot connect or loses connection when this happens.

There seems to be a massive number of httpd instances launched even when the wordpress site is doing nothing. I’ve reduced the maximum number of instances and that seems to have helped the massive mysqld blow-outs (and the putty slow-downs), but it doesn’t resolve the core problem that the site is inaccessible in either case.

Loading the theme 2016 only works some of the time.

I’ve installed the wordpress command line interface as the wp-admin page is also inaccessible. However, the wp-cli keeps insisting that the enfold stylesheet is missing.

Enfold (and this child theme) was working fine from about December to last weekend. I haven’t changed anything to do with wordpress, but I did set up an auto-sleep function to save on AWS costs about a week beforehand, which was working for about a week.
