Gunicorn 19.0 is available as of 6-23. This is a major release with many bugfixes, new features, and some deprecations. Evaluate migrating from Gunicorn 18.0 to Gunicorn 19.0 for Sync 1.5. See the full change log here: http://docs.gunicorn.org/en/19.0/news.html#id1
The changelog looks good, if nothing else it should eliminate some shutdown-related error tracebacks like those seen in Bug 1038484.
Local testing looks good, I've bumped the req version so this should get included in the next release: https://github.com/mozilla-services/server-syncstorage/commit/3895815ddb82a266106df3a85b18e719795b98f6 To verify as part of next deployment (with new syncstorage version tag).

> Are there any configuration setting changes you would recommend? None that stand out. Let's try it with the existing config and if we come across anything promising, we can tweak it further.
