That's not a crash, that says there's no connection to be read.  What would 
actually be useful, is the last data logged by slapd before the 
connection_read errors.  Given that I've had slapd run for months under a 
high read rate without any such issue, I'm guessing there something 
specific to your setup going on here.  Unfortunately, what you've submitted 
here doesn't really give any data useful for determining what that is.
