lsof shows that automount has 10288 files open, of which most of these
are like:
automount 15539 root *217u sock 0,4 595374 can't
identify protocol
automount 15539 root *218u sock 0,4 595376 can't
identify protocol
automount 15539 root *219u sock 0,4 595378 can't
identify protocol
automount 15539 root *220u sock 0,4 595380 can't
identify protocol
Upon restarting autofs, these open files are cleared out and automount
works, but the open files gradually build up again.
After setting USE_MISC_DEVICE=no, I no longer get the open file issue,
but we are trying to remedy the autofs lazy unmount / cwd issue.
Mmm .. that's not good.
I'll have a look and see what I can see.

Sorry about the initial red herring, but it looks like I'm getting the
increasing open files even with USE_MISC_DEVICE=no. I must have
previously done a grep for autofs instead of automount.
In any case, after a restart of autofs:
[r...@talon ~]# /etc/init.d/autofs restart
Stopping automount: [ OK ]
Starting automount: [ OK ]
[r...@talon ~]# lsof |grep automount | grep sock

This gradually increases with every new mount until automount has 10288
files open.
