Hi all, I just noticed the following bug - https://bugs.launchpad.net/cinder/+bug/1197648 which is very similar to an issue I recently looked at in Swift - https://bugs.launchpad.net/swift/+bug/1181146 Basically these problems are actually a result of a bug in python-eventlet < 0.13 i.e. https://bitbucket.org/eventlet/eventlet/issue/149/yield-in-except-clause-with-wilcard-raise This has now been fixed and released so please update your package and hopefully these issues will cease. Ed.
