自從一段時間以來，我遇到了這個問題（不定期），我無法再登入我的伺服器。 SSH 連線或 Web 介面登入無法登入。在控制台上登入可以正常工作，但登入後我立即再次登出。
伺服器執行 Ubuntu Server 16.04.2 (LTS) 以及所有最新更新。
當我嘗試透過 SSH 登入時，出現以下錯誤：
$ ssh wouter@Hyperion
wouter@Hyperion's password:
shell request failed on channel 0
在我強制重新啟動伺服器後，一切都會恢復一段時間。
我在 /var/log/syslog 中發現了以下內容，它與我失敗的登入嘗試之一相對應：
