 I've seen such behavior with -current systems as well. Here's what I
 have seen:
 
 Oct  5 22:07:11 myhakas mountd[150]: umountall request from 194.126.114.87 from unprivileged port
 Oct  8 20:07:38 myhakas mountd[149]: umountall request from 194.126.114.87 from unprivileged port
 Oct  8 21:34:30 myhakas mountd[149]: umountall request from 194.126.114.87 from unprivileged port
 Oct  8 23:24:50 myhakas mountd[149]: umountall request from 194.126.114.87 from unprivileged port
 Nov  2 20:02:32 myhakas mountd[150]: umountall request from 194.126.114.87 from unprivileged port
 Nov  3 09:00:48 myhakas mountd[150]: umountall request from 194.126.114.87 from unprivileged port
 
 The NFS server machine is running -current and serves 3.3-STABLE and one
 Solaris 2.6 box.
