[vserver] autofs failing to umount in guest

Seasons greetings,

In my host, automount mounts and umounts successfully. But I am not
interested in that. I want to automount in my guest.

In my guest only mounting is successful. umount is only
possible manually or by /etc/init.d/autofs restart.

/var/log/syslog records:
automount[27362]: umount_autofs_indirect: ask umount returned
busy /mnt/removables

Busy! I don't know what with. Do you good people have any ideas or
experience with this?

Regards

Fog_Watch.
