1.最近在使用spring-boot和用spring-data-mongo操作mongodb

2.每天早上查看伺服器日誌都發現報了同一個錯，估計是在一整晚沒人訪問伺服器，第二天一旦有人訪問就會發生錯誤

3.錯誤日誌為：

4.嘗試過一些解決方法，把連結mongodb的程式碼改成：

new MongoClient(new ServerAddress(env.getProperty("mongo.host"), Integer.valueOf(env.getProperty("mongo.port"))), Arrays.asList(credential), MongoClientOptions.builder()
                .socketTimeout(10000)
                .minHeartbeatFrequency(25)
                .heartbeatSocketTimeout(3000)
                .socketKeepAlive(true)
                .build());

也把伺服器（Ubuntu）ipv4的keep alive時間改成了120秒。

但是錯誤還在，希望大家指教指教，謝謝！

多半是MongoDB把Java保持的連線踢掉了(狀態變成CLOSE_WAIT，只能發資料但無法再收到)，可以從兩個地方想想辦法：

  1. 把連接池配置好（這個貌似很複雜），或者乾脆不用連接池，即socketKeepAlive設成false；

  2. 因為你的問題都出現在早上，可以檢查MongoDB有沒有凌晨重置連線的策略。

1、可能是遇到了查詢時間過長的Read，不妨看看profiling或者server log日誌的信息，找到查詢時間比較長的語句，例如超過10秒的語句，看是否能優化；

2、適當提高socketTimeout一些，看是否能緩解這種出錯的情況。

供參考。

Love MongoDB！ Have fun！
