Subject: [PATCH] when a slave experiances an error on commands that come from
 master, print to the log

since slave isn't replying to it's master, these errors go unnoticed.
since we don't expect the master to send garbadge to the slave, this should be safe.
(as long as we don't log OOM errors there)
