java - com.mongodb.MongoException$Network Caused by : java.net.SocketTimeoutException: 读取超时

Question

当我使用morphia insert documents into Mongo-DB时，总是出现com.mongodb.MongoException$Network: Write operation to server 异常，可能间隔一分钟以下是堆栈信息:

有没有人遇到同样的问题？任何建议表示赞赏。

谢谢

这是不寻常的，在正常操作期间不应经常发生。

尝试从网络/操作系统的角度进行调试，检查以下内容:

• 应用程序和 Mongo 之间的连接是否可靠？丢包率和延迟是多少？
• 应用程序和 Mongo 之间是否有足够的网络带宽？
• 应用程序/Mongo 服务器是否有任何软件/硬件故障？
• 发生这种情况时服务器是否处于高负载状态？
