Yes, those lines appear in the section for the file that froze and not in any of the other file sections.

If you google: "ERROR: Read - Error( -1, 22, Invalid argument ) - Retrying" site:forum.xbmc.org

you'll see it's quite common. I didn't find the cause, but a couple of posts reported the show up periodically (e.g. with exactly 5 minute intervals).
Yours seems to be separated by exactly one minute.

It feels like a network timeout (keepalive?) or disk spin down type delay, although you are playing a file so you'd expect disk and network to be busy.
Do you ever see it from a local file (e.g. played from USB stick?)
