These kept repeating everytime I tried to access /mnt/dos until I
restarted the system. Trying to stop the automounter through the rc
scripts failed, saying that /mnt/dos was mounted.
However, noticing the 2nd mount attempt happened _before_ the expiration
of the first, I logged the daemon debugging messages, and tried to get
it to repeat:
~# cat /mnt/dos/test; usleep 3600000; cat /mnt/dos/test

The automount process, pid 573 hung in a D state, until I pressed
Ctrl-C, when it continued normally, but without printing the contests of
the test file.

The amount for the udelay doesn't appear to be constant - I had to
adjust it by looking at the logs and reducing/increasing the value so
that they overlapped to get this to happen. As well, I'd tried this
value before, and nothing happened then. This is on an unloaded system.
Of interest is the fact that the automount daemon has running
expiration, attempting mount, _then_ expired /mnt/dos. It shouldn't be
doing this, should it? This time, I could continue automounting /mnt/dos
as normal.
However, looking through my logs, similar events (ie mounting before
expiry) have happened before, sometimes with a corresponding loss in
data in my rc5 buffers, which are symlinked from /usr/local/rc5des to
/mnt/dos/rc5des, and, according to my rc5 logs, state that, from about
20 blocks, they now have none. This has been happeneing for a while.
Automount version was 3.1.1, and kernel version was 2.1.95 for the
yesterday's results, and 2.1.97 for todays. Timeout in /etc/auto.master
was set to 3 seconds.
Hope this helps,
Bradley
