Dolph,

Thanks for the quick turn around on this,  I will try this out and let you know. It is intermittent but not hard to make happen.

Subject: Re: [openstack-dev] [Quantum] New error when creating networks

Pending feedback from Adam and a bug report, here's a potential fix: https://review.openstack.org/#/c/14865/

Any details on what file is being read twice? (I doubt this is a quantum issue -- more likely to be keystone)

I'm guessing the culprit is that the auth_token middleware reads/writes a PKI token revocation list to disk... although I'm not sure why it can't be stored in memory -- Adam?

Hi Quantum team,

Lately I have come across a new error using quantum from the "master". Never saw this before. It appears I may have updated some package and at this time I have no idea which one to back off. This may be related to some python package.

Any ideas?

2012-10-25 15:11:12    ERROR [keystone.middleware.auth_token] HTTP connection exception: Second simultaneous read on fileno 9 detected.  Unless you really know what you're doing, make sure that only one greenthread can read any particular socket.  Consider using a pools.Pool. If you do know what you're doing and want to disable this error, call eventlet.debug.hub_multiple_reader_prevention(False)

Thanks,
-Shiv
