Hi, I have the encountered following problem (https://bugs.launchpad.net/quantum/+bug/1073999). The Quantum service and qpid daemon are running on the same host. If the Quantum service starts and the QPIDD daemon is not running then the Quantum service will hang in the callself.connection.open() (https://github.com/openstack/quantum/blob/master/quantum/openstack/common/rpc/impl_qpid.py#L357). When QPID starts/restarts the Quantum service is still waiting on a file descriptor here and never recovers. The work around is to restart the Quantum service. If I comment out the lineeventlet.monkey_patch() (https://github.com/openstack/quantum/blob/master/bin/quantum-server#L25) then the logs indicate that the re-connection to qpidd is attempted - the problem here is that the RPC requires that monkey patch. Any help or input will be greatly appreciated. Thanks Gary
