Really?  Where, exactly, since it's not in stderr/stdout?

Okay, but which files/directories are the problem?

Note that I am running this as root, at least on the remote system, so it does not seem like it
could be on the target server.

However, "IO error" is fairly generic, and on an archive of 300,000
files, does not help me much.

If the error is local, it'd be nice if rsync used the standard perror to show the exact error,
and prefix it with the directory/filename.

If remote, perhaps the remote end should use perror and hte local side pick it up.

Could a dangling symlink cause this problem?

To answer the other question, no, it's not a rsync daemon.
