(In reply to Dennis Clarke from comment #0)
So, are you saying your NFS server replied with errno 130?
(There's no 130 in errno.h nor in RFC1813, the one that
covers NFSv3.)

If you can reproduce this, you need to capture packets
# tcpdump -s 0 -w out.pcap host pluto
on the client while you do the mount attempt.

Then look at out.pcap in wireshark (which knows how
to decode NFS). You should be able to see what the
actual error being replied by the server is.

Ig general, over the years various NFSv3 servers have
thrown all sorts of error numbers when they are misconfigured.
As such, I suspect the code retries for a while in the hope
that a sysadmin fixes the server.
(Usually mounts are in /etc/fstab and people don't like those
failing because a server is misconfigured. It's easier to fix
a server and then have all the clients mount successfully than
having to go around and manually get them all to mount after
fixing the server.)

These "habits" have been developed over, literally decades.
