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. -- Vallo Kallaste vallo@matti.ee To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-bugs" in the body of the message
