これ の続き。
- 週末にサーバを停止して60時間連続Memtest86。全く問題なし。
- /var/log/messageに"Unknown cmd fd(7)"とエラーを吐き続けるプロセスを停止。効果なし。
これもダメ _| ̄|○結局彼 と同じくOOM-Killerを止めました。echo 100 > /proc/sys/vm/lower_zone_protection
さて明日休み中にエラーを出すかどうか。オーバーコミット止めてるし、システム停止はない・・・と祈るw しかし・・・なんかやってない? > RedHat[参考]echo 0 > /proc/sys/vm/oom-kill
[追記]
これ書いた後に/var/log/messageを見たら、OOM-Killerが発動抑制されてた。システムは元気に稼動中。
