Have you got WP super cache set up to serve static pages?
It’s mucho weird for you to be getting heavy DHb and code errors if that is the case.
Maybe try setting WP DEBUG LOG to true in WP config? This might give you some error logging information that might help identify source of the errors.
Alternatively, i’m wondering if there’s a gremlin in one of your plugins, theme or functions.php. IF there’s a way for you to deactivate all plugins and switch to default theme, while still testing for errors, that would be ideal. I understand that’s tricky on a live site though.
There is a plugin called “duplicator” that enables you to clone your whole site, configuration, data, plugins, the lot. If you could
1) create a cloned site,
2) find a way to trigger the errors
3) deactivate plugins, switch to default theme
4) test for error
5) progressively reactivate stuff while testing for errors
that might well turn up what’s going on
