위 에러는 xinerd.conf의 per_source limitation 설정으로 인한 에러이며, 시스템 부하와 필요여부를 확인하여
per_source 값을 조정하여 해소 할수 있다.

Connection reset by peer (errno = 104)
위 에러는 whostif process가 동작중이지만 connection은 종료된 상태에서 출력된다
따라서, 해당 서비스 어플리케이션에서 disconnection 모니터링 부분을 확인하여 에러를 조절할 수 있다
Failed to contact identity server at ::ffff:172.20.241.23: error while receiving response 해당 메세지도
whostif 서버에 접속이 실채하면서 발생한 에러로 보인다.
