Apache itself is rather robust in my experience. I'm suspecting any of the backend services that could be tying Apache resources as part of the proxy process.
Are we sure all the backends are timely serving the requested responses? And that nobody is flooding Apache with requests causing backend contention?

This was a bogus diagnosis.
From what I could make of the logs, the apache2 instance which runs all of our user-facing HTTP(S) traffic quit serving shortly after midnight UTC. The cause is unclear.
I had to start/restart apache2 a couple times to clear out resources.
