Help with automounter

[Carlos Ibarra]

We are using the automounter extensively in our campus. We just upgraded
to SunOS 4.1.1 and find that every once in a while the automounter gets
stuck at a non-interruptible wait. Presumably it is waiting for some NFS
server to respond. I have noticed the load going up to around 36 with
nothing running.

What I would like to do is have it fail if the NFS server does not respond
in a second or two.

I thought the -soft option did this, but apparently, it does not. I tried
putting in a retry=20 option (default is 10000), but it seems to be
ignored when -soft is also specified. 

What mount options should I use in the automounter's NIS maps in order to
have it fail when a very slow NFS server does not answer?
