autofs hangs

Binary package hint: autofs

Hi,

After not using automounted directories for a while, autofs seem to loose track of its mountpoints.

This is what happens:

magnus@htpc:~$ ls /var/lib/mythtv/videos/remote/hmovies
ls: cannot access /var/lib/mythtv/videos/remote/hmovies: No such file or directory

magnus@htpc:~$ ls /var/lib/mythtv/videos/remote/hmovies/
ls: cannot access /var/lib/mythtv/videos/remote/hmovies: No such file or directory

magnus@htpc:~$ sudo /etc/init.d/autofs restart
Stopping automounter: done.
Starting automounter: done.

magnus@htpc:~$ ls /var/lib/mythtv/videos/remote/hmovies
ls: cannot access /var/lib/mythtv/videos/remote/hmovies: No such file or directory

magnus@htpc:~$ ls /var/lib/mythtv/videos/remote/hmovies/
ls: cannot access /var/lib/mythtv/videos/remote/hmovies: No such file or directory

It seems to be no way to get it to work again - other than rebooting the entire box.
After rebooting all automounts are accessible again. Also when using these automounts frequently it will
keep working.

magnus@htpc:~$ ls -l /var/lib/mythtv/videos|grep remote
drwxr-xr-x 3 root root 0 2010-02-28 17:35 remote

I try to restart and unmount, but somehow autofs is dead.

Also, manually mounting the same cifs share with mount works fine.
