desde algum tempo eu tenho esse problema que (em intervalos irregulares) eu não consigo mais entrar no meu servidor. Uma conexão SSH ou login da interface da web simplesmente falha ao efetuar login. Fazer o login no console funciona, mas imediatamente após o login eu saí novamente.
O servidor roda o Ubuntu Server 16.04.2 (LTS) com todas as atualizações mais recentes.
Quando tento efetuar login via SSH, recebo o seguinte erro:
$ ssh wouter@Hyperion
wouter@Hyperion's password:
shell request failed on channel 0
Depois de forçar a reinicialização do servidor, tudo funciona novamente por um tempo.
Encontrei o seguinte em / var / log / syslog, que corresponde a uma das minhas tentativas de login com falha:

Qualquer ajuda será muito apreciada.
