Comment 14 for bug 1703856

An interesting thing is we recently discovered devstack was misconfiguring apache and had apache caching all the chunked requests to send the glance api a request with a content-length. (which obviously can take more than 30secs on a large image) I'm wondering if the fix for that bug: https://review.openstack.org/#/c/492651/ will also address this. If people who are effected by this issue could test if they still have it with 492651 applied and let me know that'll be useful in ruling that out.
