며칠 사용 후 Firefox가 정지됨: CPU 제한

내 Firefox가 며칠마다 정지됩니다.

다음과 같이 표시됩니다: CPU 시간 제한 초과(코어 덤프)

이 제한을 제거하거나 최소한 늘릴 수 있는 방법이 있습니까?

chrt -o 0 firefox한동안 작동하는 것 같았지만 더 이상 작동하지 않습니다.

모든 프로세스에 대해 CPU 제한이 설정되어 있는지 확인했습니다.

grep cpu */limits|grep -v 'unlimited.*unlimited'

이것은 아무런 타격도 입지 않았습니다. 그러나 여기에는 모든 Firefox 프로세스가 나열됩니다.

$ grep realt */limits|grep -v 'unlimited.*unlimited'|G 000

이것이 이유일 수 있습니다. 그런데 어떻게 바꾸나요?
