Question

当我使用morphia将文档插入Mongo-DB时，总是会出现com.mongodb.MongoException $ Network：对服务器异常执行写操作，可能是一分钟的间隔以下是堆栈信息：

有没有人遇到同样的问题？任何建议都值得赞赏。

Answer 1

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，请检查以下内容：

应用程序和Mongo之间的连接是否可靠？数据包丢弃率和延迟是多少？
应用程序和Mongo之间是否有足够的网络带宽？
应用程序/ Mongo服务器上是否有任何软件/硬件问题？
服务器何时发生高负荷？

com.mongodb.MongoException $ Network引起：java.net.SocketTimeoutException：读取超时
