  Then one of the following is true if the content size doesn't match:

	1. The server has a bug in that it sent a malformed size.

	2. The server send a malformed file.

	2. The connction was dropped during the transfer.

	3. The client has a bug in counting the bytes being received.

  In any case, what you have may not be complete and an error (or warning)
should be presented to the operator to decide what to do next.
