> When writing to IoTDB server with multiple clients at the same time, it turns
> out that the auto create schema operation may write incorrect timeseries into
> mlog.
> It’s probably a synchronization issue. The _createTimeseries()_ in
> mLogWriter.java is not atomic, causing the content in mlog.txt not readable.
> This issue may cause errors when doing recover for IoTDB. See the screenshots
> attached.
