Output freemenunjukkan bahwa aplikasi saya hanya menggunakan 2GB, swap tidak digunakan sama sekali. Namun aplikasi saya terbunuh (Skype, Firefox, Thunderbird). Saya menontonnya htopdan sepertinya mereka mengalokasikan beberapa megabyte dan terbunuh. Saya harus reboot untuk "memperbaiki" masalah.
Pertanyaan saya adalah mengapa dan yang lebih penting bagaimana cara memperbaikinya ketika ini terjadi lagi (maksud saya selain restart)? (EDIT3)
Itu sangat menjengkelkan, saya kehilangan posting yang cukup panjang (Firefox terbunuh tanpa pemberitahuan) dan hal-hal lainnya. Apakah normal di Linux, mematikan aplikasi b / c OOM pada memori bebas 80% dan tanpa upaya untuk menggunakan swap sama sekali?
EDIT: Distribusi adalah Kubuntu 16.04.

Saya menduga itu harus melakukan sesuatu dengan tidak membebaskan io cache, sayangnya saya tidak menyimpan output free.
EDIT3: Saya pikir pertanyaan yang dicetak tebal itu ditandai dengan jelas, tetapi beberapa orang gagal membaca dan mulai menandai seluruh pos ini sebagai "tunggu apa yang Anda tanyakan" . Saya telah memberikan semua info tambahan yang diminta dan hanya memastikan judul yang diedit menjadi pertanyaan untuk menghindari situasi ketika seseorang mengabaikan teks pertanyaan dan langsung menandainya sebagai "tidak jelas apa pertanyaannya" ...
EDIT4: Terjadi lagi, pasti terkait dengan IO tinggi (membaca dari HDD). Output dari free:

cat /proc/sys/vm/swappiness.gfp_maskmenunjukkan bahwa itu tidak secara khusus meminta zona DMA32, sehingga harus dapat menarik dari normal.Jawaban:
Untuk pertanyaan Anda:
Mengapa: Anda mungkin menggunakan Kernel 4.4.0-59. Jika demikian, Anda dipengaruhi oleh bug OOM: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1655842 .
Cara memperbaikinya ketika ini terjadi lagi: Turunkan kernel Anda ke misalnya. 4.4.0-57.

4.4.0-59-generic). Saya akan mencoba downgrade, terima kasih atas sarannya.
