>Description:
There is a needed patch for quagga, specifically bgpd that prevents it from leaking memory.  On a busy router, it leaks about 1MB every 10min. Description of the problem and patch are found 
http://lists.quagga.net/pipermail/quagga-users/2011-October/012529.html

>How-To-Repeat:
startup quagga with bgp and a full table.  Watch memory usage grow.
>Fix:
--- bgpd/bgp_attr.c
+++ bgpd/bgp_attr.c
@@ -675,6 +675,7 @@ bgp_attr_unintern (struct attr **attr)
     }

   bgp_attr_unintern_sub (&tmp);
+  bgp_attr_extra_free (&tmp);
 }

The above patch can be added into the files directory of the port and I added 
PORTREVISION=   1
to the port's Makefile
