運作寫的不太完善的爬蟲程式, 未限制任務隊列大小, 再加上本子配置不高, 爬取網站到第3層大半時, 記憶體不足了...
程序運作太猛, 導緻系統 out of memory, 那麼此程序被系統的oom killer殺死.
此時終端顯示 "Killed" 或 "已殺死".
檢視相關資訊的指令:
dmesg | egrep -i -B100 'killed process'
或:
egrep -i 'killed process' /var/log/messages
egrep -i -r 'killed process' /var/log
或:
journalctl -xb | egrep -i 'killed process'
結果類似這樣:
4月 07 10:48:58 arch kernel: Out of memory: Kill process 1245 (python) score 685 or sacrifice child
4月 07 10:48:58 arch kernel: Killed process 1245 (python) total-vm:3519016kB, anon-rss:2453976kB, file-rss:0kB
