I am considering what NFS mounting options should be used in a large collection of automount maps being used over a large number of hosts (>500). Of note, there is a collection of machines, both Linux (RH, Suse) and UNIX (Sun, AIX, HP/UX). Also, there is automount support provided for hosts outside the US. What I have been considering is the following options in the maps:
intr,bg,soft,retry=10,timeo=600,retrans=10
I have not specified rsize or wsize as I understand that the largest size between the host and the server is negotiated.
What do you all use or recommend?

As you can't specify more for autofs then any regular NFS mounts all the caution regarding NFS applies. The rsize and wsize parameters have non-maximum defaults but will be negotiated when you set it to something very large and you have to check
/proc/mountsto see what was negotiated. Generally your settings seem fine to me as a NFS service interruption taken care of in your case due to theintr,bg,timeoet al.Do I understand that correctly, you mount NFS via a WAN?
