    Hi birdyfan919,

    When you see this error in the server-side log, are there any consequences for the user? If not, this is probably a harmless error indicating that a browser aborted an attempt to download media.

    This can happen with some page structures if the browser ends up doing two concurrent downloads for the same file. When the first one completes the browser drops the second connection, producing an error like the one you posted.
