Hi,

I recently installed a new machine for testing NFS mounts. Things worked
great, so I went to attend to other things. I tested the NFS mounts with
my work machine as the server. Now I regularly upgrade my work machine, so it
gets reboot every couple of days. I forgot that the client still had
/usr/ports (and only /usr/ports) mounted from my work machine, so I didn't
unmount that first. In fact, I failed to look at the client for a few days.

What I didn't notice at first was that the client failed to report its
security status from then on. I didn't get any daily mail from that machine
anymore.

Today I found out that I had a stale mount hanging around on the client. After
turning my work machine into an NFS server once again, my 'cd /usr/ports'
got unstuck (of course). However, I instantaneously got all delayed
security mails from last week onward, all of which had kernel log
messages like this

pcwin165.win.tue.nl kernel log messages:
> nfs server pcwin002:/usr/ports: not responding
> nfs server pcwin002:/usr/ports: is alive again

Now, I know for sure that I only had /usr/ports mounted during the time.
And I think it's very strange that the daily security check would fail
to mail me when a mount of /usr/ports is failing. Can anyone explain
why this would happen? I don't think the security mail should be delayed
for a reason like this.

FWIW, I don't have weekly_status_pkg_enable set, and I can't think
of anything else in periodic that needs /usr/ports. The client is
running FreeBSD 4.3-RC #0: Tue Apr  3 10:28:00 CEST 2001.
I don't have anything interesting in rc.conf, but I'll gladly
provide it if required.

--Stijn
