에러를 유발하는 ,
IndexKeyFile.scala 의 95라인

if(looping > conf.log_index_traversal_warning_count) {
Logger.println("S152", 10, "[warn] too many index deep searching. " + (if (key.length == 7) DataInputX.toLong(key,0) else ....

부분의 log_index_traversal_warning_count 값을 100 -> 1000 으로 변경하여
회피하는 것으로 설정하여 더이상 나지는 않게되었습니다.

해당 설정값이 무엇을 의미하는지요.

CPU 이슈는 .data file 이 커져서 발생하는 문제 확인 , 삭제 후 cpu 감소 확인.

위에 언급한 로그는 경고성 로그입니다. index가 너무 깊어지면 자원 소모량이 많아지게 됩니다. 이 상황을 인지하여 index 사이즈를 늘이거나 하는데 활용하기 위한 참고 정보로 생각하시면 됩니다.

text_service.data 파일이 20G 이상 커지면서 발생하였는데,

hook_service_patterns=com.xxx.proxy.tcpserver.ReactorTcpServer.*, .... 등으로 모두 class 를 등록하였으나,

xlog 에 다음과 같은 service 들이 찍히고 있어 , 최종적으로 text_service.data 파일이 커지는것 아닌가 싶습니다.

service = 00000040HDC.....
service = 00000040KMS.....

이런 것들은 service 가 아닌 , 실제로 통신할때 주고 받은 값들인데,
pattern 에도 맞지 않는데 , 왜 xlog 에 찍힐까요
