Can you tell me more about this? Did this just appear in the log? Or
did it affect a web request? Was there any negative effect other than
the message in the log? (I suppose the client disconnected and reconnected.)

One possible explanation is that the transaction was aborted before
the iterator opened the file. If this is the case, then the error is
mostly harmless.

In any case, I need more information to decide how to proceed.
