Are the mounts that are failing on the same network/subnet? You may find that you are having some issues with the network and not really the client. Have you tried mounting these via TCP instead of UDP? If the TCP stops the alerts, I would take a look at the network.

I'm testing a failover solution for NFSv4 on RHEL6 with latest updates.

nfsd(1M) nfsd(1M)
NAME
nfsd - NFS daemon
SYNOPSIS
#_conn] listen_backlog] protocol] device] [nservers]
DESCRIPTION
is the daemon that handles client file system requests. Only users with sufficient privileges can run this daemon.
The daemon is automatically invoked if and in the file.
By default, starts over the TCP and UDP transports for version 2 and version 3, and over TCP for version 4, if NFS version 4 is enabled.
One can change this with the option.
A previously invoked daemon started with or without options must be stopped before invoking another command.
Administrators wanting to change startup parameters for should make changes (as root user) to the NFS default file (see nfs(4)). Adminis-
trators can either edit this file or use the command to make changes.
Options
The following options are supported:
Start a NFS daemon over all available connectionless and connection-oriented transports, including UDP and TCP. Equivalent to set-
ting the parameter to in the NFS default file.
This sets the maximum number of connections allowed to the NFS
server over connection-oriented transports. By default, the number of connections is unlimited. Equivalent to the parameter
in the NFS default file.
Set connection
queue length for the NFS TCP over a connection-oriented transport. The default value is 32 entries. Equivalent to the
parameter in the NFS default file.
Start a NFS daemon over the specified protocol.
Equivalent to the parameter in the NFS default file.
Start a NFS daemon for the transport specified by the given device.
Equivalent to the parameter in the NFS default file.
Operands
The following operands are supported:
This sets the maximum number of concurrent NFS requests that the server can handle. This concurrency is achieved by up to nservers
threads created as needed in the kernel. nservers should be based on the load expected on this server. 16 is the usual number of
nservers. If nservers is not specified, the maximum number of concurrent NFS requests will default to 1. Changing the value of
nservers requires stopping and restarting Equivalent to the parameter in the NFS default file.
Notes
A directory service that provides service name data base support must have the following service entries in its database:
If the kernel tunable (see nfs_portmon(5)) is set to 1, then clients are required to use privileged ports (ports < IPPORT_RESERVED) to
receive NFS services. This tunable is set to 0 by default. Use (see kctune(1M)) to set this tunable.
By default, the NFS version 4 server is disabled. In order to enable it you must stop the NFS server. As root, either use the command (see
setoncenv(1M)) or edit to set the parameter to 4.
EXIT STATUS
Daemon started successfully.
Daemon failed to start.
WARNINGS
Manually starting and restarting is not recommended. If it is necessary to do so, use the NFS server start/stop script
FILES
client machine pointer to an open-but-unlinked file.
shell script for starting
startup parameters for
directories used by the server to manage client state
information; these directories should not be removed.
