>Description:
as described in freebsd bug bin/61084, the NetBSD nfsd may exit in response to a portscan, with the message:

   nfsd[318]: accept failed: Software caused connection abort


>How-To-Repeat:

>Fix:
a patch is provided in the FreeBSD bug referenced above, but I have not evaluated it, and it doesn't look like the FreeBSD people have either.
