COR ont service is down

[graybeal]

The ont service is not responsive:

Proxy Error
The proxy server received an invalid response from an upstream server.
The proxy server could not handle the request GET /ont.
Reason: Error reading from remote server

The page at cor.esipfed.org is responsive, and the AWS instance is up.

I've contacted Annie (Carlos is out) and we'll look at this in the morning.

Seems like it was Allegrograph the container that started misbehaving, that is, not responding to some request from the ORR container.

I just restarted Allegrograph and all seems back up.

To make sure the triple store is up to date, I also jsut ran the "reload triple store" function using the Admin UI at http://cor.esipfed.org/ont#/ts

Sorry, not much time now or tomorrow to do a more thorough investigation ... but two quick ideas to keep in mind:

• upgrade allegrograph (as already suggested elsewhere)
• include some timeout in requests from ORR to more gracefully handle the case where allegrograph stops responding.

Created mmisw/orr-ont#65 and mmisw/orr-ont#66 to capture those ideas.
