Hi,
since upgrading to High Sierra (Mac Mini 2012, i7, 16GB, 500GB Crucial SSD), I've had a huge amount of problems.
I've now tracked it down to the fact that Mail.App (and/or Spotlight) seems to hang at some point.
Well, it doesn't quite hang, but it gets slower and slower and ps(1) shows that it is in "uninterruptible wait".
I'm also unable to quit, force-quit or kill -9 it. I can't even reboot properly.
It's shown to be in state "E", which means that "The process is trying to exit."
As a result, to reboot I have to do a hard power-cycle with the power-button (thank god they still fitted power-buttons back then...)
I have about 1 million emails on my own IMAP server.
Maybe it's Spotlight choking on that amount of mails, I don't know.
I had zero problems on El Capitan (but the lack of security updates was a bit annoying).
I'm not sure, but I realized just now how many daemons and services macOS runs in the background these days...
Not running Mail.app has also helped getting TimeMachine backups running again.
It's a huge problem, as I like Mail.App and it's powerful search function.
