Just a final note -- I'm finally back in person with the CentOS 7 server and so booted it to the latest kernel-ml from elrepo. It is a 4.1 kernel. But while still remote with the older 3.10 kernel, I also tried doing a 'mount -oremount,clear_cache /' I can't swear it helped, but things did seem to get better afterwards... so it may be worth a try for anyone reading this thread with a similar problem later. (Unless someone can definitively say that clear_cache doesn't work with -oremount.)
