Configuration page WSOD when Tomcat is down

[seth-shaw-unlv]

If Tomcat is down when visiting the general configuration page '/admin/config' will WSOD and report to the log GuzzleHttp\Exception\ConnectException: cURL error 7: Failed connect to 127.0.0.1:8080; Connection refused (see http://curl.haxx.se/libcurl/c/libcurl-errors.html) in GuzzleHttp\Handler\CurlFactory::createRejection() (line 185 of /var/www/html/drupal/vendor/guzzlehttp/guzzle/src/Handler/CurlFactory.php)..

To be honest, I don't know why the general configuration page crashes when Tomcat is down, but it does.

To reproduce:

1. Spin up a box
2. Visit `http://localhost:8000/admin/config' which should load fine.
3. vagrant ssh
4. sudo systemctl stop tomcat8
5. Visit `http://localhost:8000/admin/config' which will WSOD.
6. Visit the recent log messages page (http://localhost:8000/admin/reports/dblog) and see the error listed.

Yes, I've noted this issue as well.

I think this has something to do with Islandora config's trying to look up fedora, but as Seth noted, not sure what on that screen.

I thought that this was traced to the fly system

@wgilling, that is what @dannylamb was postulating last meeting, but we haven't followed up on it yet.
