Mongodb Mongo secondary自动进入恢复状态并被卡住

我使用的是mongodb 2.6.5，有一个3节点的副本集。很多时候，我看到辅助节点进入恢复状态，尽管我没有尝试进行任何同步或其他操作。不确定mongo是否在后端执行此操作。这种状态从没有恢复过。我看到了许多线程，它们告诉我如何从恢复状态恢复到辅助状态，但我正在查找它，以找到为什么它将进入恢复状态的问题。是否存在任何可能导致此情况的配置

我的辅助服务器上的几行日志（我觉得可能有用）用于恢复。192.168.12.155:5000为主节点，192.168.12.154:5000为次节点。以下日志取自192.168.12.154
