EN 설치를 위해 최신 chaindata를 받아 fast sync 중입니다. 아래와 같은 Bad Block 에러(여러 블록에서)와 “too many open files” 에러가 계속해서 발생합니다. 에러가 발생해도 block sync 가 재개되긴 하지만, sync가 중단되며 kend down 되기도 합니다. 그렇게 최신블록까지 동기화를 했을 때에 정상적으로 동기화가 된 것인지도 확신이 없습니다. 어떤 문제인지 파악하실 수 있을까요? ```auto INFO[04/25,08:50:25 Z] [5] Inserted a new block number=88723885 hash=6293f0…cde603 txs=6 gas=314439 elapsed=34.799ms processTxs=2.267ms

안녕하세요. 클레이튼 포럼에 글을 남겨주셔서 감사합니다. 혹시 바이너리 버전 및 OS 공유 가능하신가요? klaytn docs에 나와있는 하드웨어 스펙에 질문자님 EN 스펙이 맞는지도 궁금합니다. ---

안녕하세요 디스크 스펙도 알려주실 수 있나요? leveldb에서 발생하는 이슈인거같은데 도커 이미지로 띄워보시겠어요? 아래 cypress docker-compose 참고부탁드립니다. > **[GitHub - deeean/klaytn-dev: 클레이튼과 관련된 개발을 할 때 필요한 리소스를 정리합니다.](https://github.com/deeean/klaytn-dev/)** > > 클레이튼과 관련된 개발을 할 때 필요한 리소스를 정리합니다.

디스크는 Amazon EBS gp3 IOPS 3000 이상입니다. 하드웨어 스펙 문제는 아닌 듯 합니다. Level DB 쪽 버그라 생각되면 공유하겠습니다.
