If it is any help, the faillure in communication always occurs at exactly 5min2 sec into the book list transfer.

Someone previously had posted about a similar timeout problem (about two years ago) and it was apparently resiolved by uninstalling and reinstalling CC. I have not done that yet; don't know why I should, but I will if that seems to make sense.

If it is any help, the debug log from cc at the point of failure looks like this. Error involves writing to a broken pipe:
