That's potentially normal -- this is a stream-level sendme from the client
to the service. The service will expect to get one of these after sending
250KBytes. If the service finishes sending the file, it will send an end
cell, thus closing the stream from its perspective. If the end cell is
heading toward the client, while the sendme cell is heading toward the
service, then when it arrives at the service, the service will no longer
remember what stream 64043 was.
