Sometimes I see 'stale NFS handle". In that case, restarting autofs
doesn't help. I use  fuser or lsof to figure out what processes are
accessing the dead thing, then kill those processes. Restarting autofs
after killing all such processes seems more likely to work. I'm not
sure the issue is completely resolved in my case, and YMMV.
