[Rocks-Discuss]Kernel error issues

I've seen this on other systems and only have a hunch --- I believe it 
is an error in some
of the common code of the network drivers. I recommend getting redhat's 
errata kernel.
Have run this on a heavily used NFS server and have not seen these sorts of
errors (they might still be there, by the frequency is reduced)

Try the following

In the "force" directory eg.

do the following:
wget ftp://acs-mirror.ucsd.edu/linux/redhat/updates/7.2/en/os/i686/'kernel*'

(you can pick a different redhat mirror)

The re-run rocks-dist form /home/install

(verify the soft links in
/home/install/rocks-dist/7.3/en/os/i386/RedHat/RPMS point to the
RPMS you just downloaded).

re-kickstart your nodes -- they will have the latest kernel
