Open Stack

Ivan,

Thank you for your reply.

As I noted near the bottom of my email, I came across this bug and suspected it was the cause, but even after upgrading to keystonemiddleware 1.5.3 I am still experiencing the issue. Am I stuck waiting for an updated of glanceclient as well or does this just impact users who pulled down the affected version of urllib3 during a specific time period?

Any advice on a workaround would be appreciated.

Regards,

Richard

Whenever this occurs, the Glance API logs look clean and I see a 200 response to each request, however the Nova API logs show an ‘AttributeError’ (http://paste.openstack.org/show/480853/) for each request. I had originally thought this was related to this bug (https://bugs.launchpad.net/glance/+bug/1476770), but am still experiencing it with keystonemiddleware 1.5.3, requests 2.8.1, and urllib3 1.12.
