오늘 갑자기 동기화가 느려지는 현상이 일어 납니다.
엄청 느리게 동기화가 진행 되는데 로그사에서는
IO 속도나, 인터넷 회선 문제, CPU, 메모리 상황은 정상인데, 왜이렇게 느린지 이유를 모르겠습니다.
안녕하세요.
The posting guideline of Klaytn 가이드 글을 확인 부탁드리고 상세한 리포팅 부탁드립니다

안녕하세요. 위에 로그는 운영하는 EN Node에서 나오는 동기화 로그를 캡처 한것 입니다.
오늘 갑자기 동기화가 밀리는 현상이 발생 하였는데요.
klay.syncing
{
currentBlock: 80805768,
highestBlock: 80833685,
knownStates: 0,
pulledStates: 0,
startingBlock: 80801408
}
현재 3만 블럭이 밀려 있는 상태입니다.
서버 리부팅후에는 조금 나아 지긴 했는데 여전히 느린 느낌은 듭니다.
