我在python中编写了一个脚本，用pymongo填充Mongodb数据库。运行脚本后，我得到以下日志：
cmd command: insert { $msg: "query not recording (too large)" } keyUpdates:0 numYields:0 locks(micros) w:48 reslen:40 175ms
通过在线研究，我发现这与Mongodb生成的两种日志的维护有关，而不是文件插入。
然后，只是为了检查，我修改了我的脚本中的以下代码
connection.dbName.collectionName.insert(document)
到
print connection.dbName.collectionName.insert(document)
我得到的输出，即输入文件的_id's：
...
149 record entered
54636c409c2e912fbf433622
150 record entered
54636c409c2e912fbf433623
151 record entered
54636c409c2e912fbf433624
152 record entered
54636c409c2e912fbf433625
153 record entered
54636c409c2e912fbf433626
154 record entered
...
正在生成_id's，但是当我在mongo shell中使用db.collectionName.findOne()时，我得到null作为输出。
我还必须说清楚Mongodb服务器是在NUMA机器上运行的。在线查看我能够解决此问题。
请帮我解决这个问题。

这就是日志所说的一切。我不明白的是，日志只显示输入的第一个文档。这是我烦恼的根源吗？
