NFS Locking Failure and Updating

[solderboy]

I have a general question about installing updates and wanted to get some advice from experts.

First: I have NFS Locking failures on shutdown. Is this a bid deal? Should I even worry about it?

Second: I have read and googled a lot about this problem and it seems that it is supposed to be fixed with nfs-utils-1.0.7-16. I have already updated my machine via yum update and apt-get update . When I do a yum search, I get:

[root@Mr-Burns ~]# yum search nfs-utils

nfs-utils.i386                           1.0.7-8                base
Matched from:
nfs-utils
The nfs-utils package provides a daemon for the kernel NFS server and
related tools, which provides a much higher level of performance than the
traditional Linux NFS server used by most users.

This package also contains the showmount program.  Showmount queries the
mount daemon on a remote host for information about the NFS (Network File
System) server on the remote host.  For example, showmount can display the
clients which are mounted on that host.

It appears that I only have 1.0.7-11 installed. How can I find out if this is the latest released version? If it is, should I try to install an unreleased 1.0.7-16 to fix my problem, or am I just asking for more headaches?

Finally: Can I just turn off NFS locking using a chkconfig command? What will happen if I just decide to not use NFS Locking?

Thanks!
