我想写一个解析器，而且我正在使用MongoDB作为数据库。本质上它正在经历，创建对象，然后保存它们。它每秒要做几次。经过周围164对象保存它崩溃，出现此错误：MongoDb大量节省“isOK（）checkWriteError”异常
com.mongodb.MongoException: isOk() at com.mongodb.DBTCPConnector._checkWriteError(DBTCPConnector.java:130) at com.mongodb.DBTCPConnector.say(DBTCPConnector.java:142) at com.mongodb.DBApiLayer$MyCollection.insert(DBApiLayer.java:141) at com.mongodb.DBApiLayer$MyCollection.insert(DBApiLayer.java:97) at com.mongodb.DBCollection.insert(DBCollection.java:61) at com.mongodb.DBCollection.save(DBCollection.java:547) at com.google.code.morphia.DatastoreImpl.save(DatastoreImpl.java:638) at com.google.code.morphia.DatastoreImpl.save(DatastoreImpl.java:685) at com.google.code.morphia.DatastoreImpl.save(DatastoreImpl.java:679) at com.soleo.internal.releasenotes.orm.Storage.save(Storage.java:764) at com.soleo.internal.releasenotes.page.MainPage$2.onSubmit(MainPage.java:256)
现在在一个点，我在这同一个数据库中超过1000个对象，我只是没有把它们插入的一次。所以它不能成为硬盘空间问题。我在网上找不到任何有关此错误的文档。奇怪的是，只有当我尝试保存这个对象。如果我在崩溃后尝试保存对象B，它可以节省很多。它刚刚在对象A上崩溃，这是我最初保存的那个对象。
我跑了一个测试多次，它在同一个地方失败。我用随机值，所以我可以证明这不是一个变量的问题：

这里的一些部分混淆代码：
Random blank = new Random();
ObjectRef blah = new ObjectRef("iHateYou");
storage.save(blah);
for(int i = 0; i < 300; i++)
{
System.out.println("==============================\nCREATING OBJECT #" + i);
ObjectA saveMe = new ObjectA();
saveMe.setRef(storage.getRefByName("iHateYou"));
System.out.println("Component: " + saveMe.getRef.getName());
saveMe.setLocation(blank.nextInt(300000) + "");
System.out.println("Location: " + saveMe.getLocation());
saveMe.setVersion(new Version(blank.nextInt(9) + "." + blank.nextInt(9) + "." + blank.nextInt(9) + "." + blank.nextInt(9) + "-" + blank.nextInt(9)));
System.out.println("Version: " + saveMe.getVersion());
try

saveMe.setReleaseDate(new SimpleDateFormat("MM-dd-yyyy").parse(randomDate));
System.out.println("Date: " + saveMe.getReleaseDate() + " (" + randomDate + ") ");
}
catch (ParseException e)
{
e.printStackTrace();
}
System.out.println("SAVING.............");
storage.save(saveMe);
System.out.println("SUCCESS.");
