我們正在使用Titan-1.0.0支持備份爲cassandra 2.1.7。該集羣由36個VM組成，每個16GB RAM（6GB堆積）和16個CPU核心。我們正在使用SSD磁盤來處理cassandra數據，而正常的硬盤使用commitlogs。 RF爲3，讀取/寫入每個CF = 2。 Java版本爲1.8.0_45通過此羣集提供重讀。我們正面臨一些服務器的隨機停機，服務器停機一天的時間間隔約爲兩倍。讓我分享一個特定的實例，大概10-May-2017 04:00 AM，有太多的READ/MUTATION下降，我們不得不重新啓動服務器。以下是我們在服務器故障時收集的一些參數：Titan/Cassandra讀取可伸縮性，隨機服務器關閉或丟失信息
有人可以請幫助我們一些指針，至於這裏出了什麼問題，以及可以如何穩定服務器。
