Hm. Well, I did find a bug in ypserv/yp_dblookup.c:yp_next_record()
which looks like it might be the cause of your trouble. I've committed
the fix to the RELENG_2_2 and -current branches. Since it's small, here's
a patch:

*** yp_dblookup.c	Mon Jan 13 23:20:26 1997
--- yp_dblookup.c.new	Sun Jan 19 19:20:09 1997
***************
*** 600,607 ****
  		rval = yp_first_record(dbp,key,data,allow);
  		if (rval == YP_NOKEY)
  			return(YP_NOMORE);
! 		else
  			return(rval);
  	}
  
  	if (ypdb_debug)
--- 600,612 ----
  		rval = yp_first_record(dbp,key,data,allow);
  		if (rval == YP_NOKEY)
  			return(YP_NOMORE);
! 		else {
! #ifdef DB_CACHE
! 			qhead.cqh_first->dbptr->key = key->data;
! 			qhead.cqh_first->dbptr->size = key->size;
! #endif
  			return(rval);
+ 		}
  	}
  
  	if (ypdb_debug)


Please let me know if this changes ypserv's behavior, one way or the other.
