https://github.com/Azure/sonic-buildimage/issues/5255 Root Cause: Waiting on Restore count != 0 can lead to race condition between orchagent process and swssconfig.sh. Ideally check of Restore count != 0 is not needed as the State DB cannot be flushed as if it was flushed then Warm Restart or swss-restart should not be true also.
