This indicates a client disconnecting without sending a polite goodbye
(namely a Terminate or 'X' message). This isn't really dangerous,
unless the client failed partway through a transaction; but still you
might want to clean it up to avoid the chatter in the log.
Some of our client libraries used to be in the habit of just
disconnecting, so if you're using older client libraries then an update
is the first thing to try.
Otherwise, it's likely an application programming bug, ie, quitting
without closing down your database connections first.
