It might or might not be relevant: one of my 1.4T/sparc machines rarely
survives more than about 50 days of uptime without crashing "malloc:
out of space in kmem_map".  I have so far not managed to track down the
leak (when an edit-test-debug cycle takes two months, debugging is not
fast), so it's pure speculation that it even has anything to do with
networking.

But it might be worth at least considering the possibility that what
you're seeing is a very old issue.
