Open Stack

Hi All,

Recently, I've been having trouble running stack.sh from scratch. With the default configuration I've been using for a while, I get the following error in /opt/stack/logs/key.log:

2016-04-19 16:05:26.630 22047 DEBUG keystone.common.controller [req-3d384c1f-8b9a-4ff0-aa30-a4aad73963fb 3bdfb473e0e544a4a1889c9192d2ba3c fd622e15c12a49a299a63022c5d34088 - default default] RBAC: Authorization granted inner /opt/stack/keystone/keystone/common/controller.py:180

    raise ArgsAlreadyParsedError("cannot register CLI option")
ArgsAlreadyParsedError: arguments already parsed: cannot register CLI option

As a workaround, I've set, in local.conf,  
       KEYSTONE_USE_MOD_WSGI=False 

And this seems to solve the issue (meaning, stack passes with no errors - have not done extensive testing of functionality). 

Does anyone else experience this? Any other suggestions to fix this?

Thanks
