メモリからコンピュータを実行して過度の操作を実行した後、大量のメモリが解放されるまでコンピュータは応答しません。
私のコンピュータは16GBで、画像は約3.5GBで、intellij、mavenなどを実行しています。私はまだ16GBだけでなく、12GB以上を確保することを想像することはできません。このような状況に近い場合は、応答しないよりも「メモリを割り当てることができません」というエラーメッセージが表示されるほうがよいでしょう。
マイメモリ設定：
vm.oom_dump_tasks = 1
vm.oom_kill_allocating_task = 0
vm.overcommit_kbytes = 0
vm.overcommit_memory = 2
vm.overcommit_ratio = 100
vm.swappiness = 60
この問題のシミュレーション中に発生した唯一のエラーは次のとおりです。
