"rpc mount export: RPC: Can't decode result" when export list is to long

Well, "showmount -e" queries the server's mountd. I don't know of a
limitation (except maybe the maximum size of a UDP datagram), but as
far as I am aware, it will only report entries in /etc/exports. Your
email would suggest otherwise and since I'm not up to speed w.r.t. how
ZFS's sharenfs command works, I can't help...

You might want to try putting the exported file systems in /etc/exports
instead.

I'm also a bit surprized that automount cares what the mountd protocol
thinks is exported but, again, I'm not up to speed on what automount
actually does.

Sorry I can't be of more help, rick
