ubuntu系統(tǒng)卡住原因分析

有若干臺(tái)ubuntu14.04服務(wù)器，無法ping通，接上鍵盤和鼠標(biāo)依然無法操作，只好重啟，結(jié)果syslog中有如下日志，從這些日志中能看出什么嗎？

從zabbix監(jiān)控來看，是這條日志后，監(jiān)控獲取不到數(shù)據(jù)了，'org.freedesktop.systemd1'

鬧劇一場(chǎng)，上面的內(nèi)容是主動(dòng)重啟服務(wù)器時(shí)的日志記錄。節(jié)點(diǎn)1掛了，客戶搞錯(cuò)了去重啟節(jié)點(diǎn)2才出現(xiàn)了上面的日志。沉痛的教訓(xùn)，忙活大半天。
