আমার একটি উবুন্টু 12.04 সার্ভার রয়েছে যা কখনও কখনও সম্পূর্ণরূপে মারা যায় - কোনও এসএসএইচ, কোনও পিং, শারীরিকভাবে পুনরায় চালু না হওয়া পর্যন্ত কিছুই না।
পুনরায় বুট করার পরে, আমি সিসলগে দেখছি যে ওম-হত্যাকারী হত্যা করেছে, বেশ, সবকিছুই।
এগুলিতে অনেকগুলি মেমরি ব্যবহারের তথ্য রয়েছে। OOM ইস্যুটির কারণ কী হয়েছে তা দেখতে আমি এই লগগুলি কীভাবে পড়ব? সার্ভারটির প্রয়োজনের তুলনায় অনেক বেশি মেমরি রয়েছে, তাই এটির স্মৃতিশক্তি শেষ না হওয়া উচিত।
