Saída de freemostrou que meus aplicativos usam apenas 2GB, swap não foi usado. No entanto, meus aplicativos estavam sendo eliminados (Skype, Firefox, Thunderbird). Eu assisti htope parecia que eles alocaram alguns megabytes e foram mortos. Eu tive que reiniciar para "corrigir" o problema.
Minha pergunta é por que e mais importante, como corrigi-lo quando isso acontecer novamente (quero dizer, além de reiniciar)? (EDIT3)
Foi muito chato, perdi um longo post (o Firefox foi morto sem aviso prévio) e outras coisas. É normal no Linux matar aplicativos b / c OOM com 80% de memória livre e sem nenhuma tentativa de usar swap?
EDIT: A distribuição é o Kubuntu 16.04.

Eu suspeito que ele tenha algo a ver com não liberar o cache io, infelizmente eu não salvei a saída do free.
EDIT3: Eu pensei que a pergunta em negrito estava claramente marcada, mas algumas pessoas não conseguiram ler e começaram a marcar todo esse post como "em espera, pois não está claro o que você está perguntando" . Forneci todas as informações solicitadas adicionais e, para ter certeza, o título editado é uma pergunta para evitar situações em que alguém ignora o texto da pergunta e o marca imediatamente como "claro o que é a pergunta" ...
EDIT4: Aconteceu novamente, definitivamente relacionado ao IO alto (leitura do HDD). Saída de free:

Para suas perguntas:
Por que: Você provavelmente está usando o Kernel 4.4.0-59. Nesse caso, você é afetado por um bug do OOM: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1655842 .
Como corrigi-lo quando isso acontecer novamente: Faça o downgrade do seu kernel para, por exemplo. 4.4.0-57.

4.4.0-59-generic). Vou tentar fazer o downgrade, obrigado pela sugestão.
