I doubt it. The data is stored externally in the filesystem and referenced in the SQLite database. I guess something happens in the filesystem or during every second storing process, so that the metadata references become out of sync.
I'd guess it's because someone isn't accessing it from a single thread, or isn't following the lifecycle requirements for storing data in an asynchronous datastore.
You absolutely have to wait for the completion event for a write before issuing another write to the same key for example.
