Kernel BUG

kernel을 건드리는 작업을 한 것은 아니고 그냥 CPU, memory를 많이쓰는
string match 같은 일을 많이하는 서버인데요.
어느 날 이유없이 죽어서 리부팅해보니 /var/log/message에 'kernel BUG'라고
나와있네요.
(그 전까지 몇 달간 같은 프로그램이 잘 돌고 있었거든요.)
커널 패치해서 버젼을 올리는 게 좋을 까요?
제가 짠 작은 프로그램의 문제인지.. 커널의 문제인지(커널 버그라니;;)

@ 그냥 linux kernel이 이 정도 확률로 죽는 건 감수해야 하는 건가요?;;

-------------------------------------------------------
kernel 코드가 assert를 만나 fail이 난듯.
커널 모듈 중 하나의 문제일 수 있음.
