Looks like this is happening in oslo-incubator/openstack/common/log.py:

https://github.com/openstack/oslo-incubator/blob/36e5c2d26719d58aa31e4f0f4dccc50d6d996b8f/openstack/common/log.py#L486-L495

This should be fixed in oslo-incubator and moved over to Keystone in the next sync.

Working on a patch.

Steps to reproduce

1.) set use_syslog=true in keystone.conf
2.) make sure rsyslog(syslog) process is not running
3.) restart Keystone

    Except socket.error if syslog isn't running

    When setting `use_syslog=true` and restarting the service, if syslog (or
    rsyslog) isn't running, except the error and inform the user instead
    of failing with a generic Errno 111.
