Yeah, lets start with an explanation of what happens.
This is not about memory leak, rather an eternal recursion
in route processing due to (I think) canonicalization
problem on the source address.
Try following in interactive mode:
z# router '"<>"@mx05.netaddress.usa.net'
(... lots of text zips in front of your eyes...)
Now scroll back (you have LONG scroll-back buffers, don't you?)
and see where it goes into loop..
My guess it is inside canon while processing "<>" :-/
I may have time tomorrow to look at this -- I hope I will
