Canada is not the US, and OHIP has rules differently than others.

True, but several Quebecois Universities doesn't seem to have a problem with Amazon Montreal. :)

And the clinic would like to survive having our third-world telco go down.

LOL. At first, I was thinking "Amazon US" was the "third-world telco", then it occurred to me that you meant your own connection :)

OSCAR has a .deb that tries to be all singing, all dancing.
It's not the only solution.

Well, privately-distributed .deb files are really just a "help" to system admins, as long as the admin agrees with everything the packager has done. It sounds like the .deb package is really built for dev-test and not for production. Shame. You should ask them to offer both.

Exactly.

Same 100% CPU.

okay, I'll try again and post the result.

It's not happening.

/me is confused.

okay.

The suspense is killing me.

BTW I'd be happy to continue helping-out via this mailing list for free, at least until I get busy or lose interest. I'm also happy to consult off-list for NOT free if you need that kind of attention. I have some experience with production health care systems running on Tomcat + MySQL/MariaDB.
