Comment 1 for bug 1472988

Issue can be recreated if security group id is explicitly assigned and schema is restarted.

I patched the setup to convert the security-group id to int() before calling zk api.

    def set_configured_security_group_id(self, config_id):
        if self.config_sgid == config_id:
            return
        self.config_sgid = config_id
        sg_id = self.obj.get_security_group_id()
        if config_id:
            if sg_id is not None:
                if int(sg_id) > SGID_MIN_ALLOC:
                    self._sg_id_allocator.delete(int(sg_id) - SGID_MIN_ALLOC) <<<
                else:
                    if self.name == self._sg_id_allocator.read(int(sg_id)): <<<
                        self._sg_id_allocator.delete(int(sg_id)) <<<
            self.obj.set_security_group_id(str(config_id))
        else:
