NFS server becomes unresponsive when bond 6 mode is used on RHEL 6.5

Issue

• After a scheduled reboot on one of my servers, NIC bonding is causing network connectivity to behave erratically. As most users /home directories live on a remote NFS server, this translates to general slowness at the shell, either when running any command, or by attempting tab-autocompletion. All users also include an NFS-mounted /software tree in their PATH. I created a test user with a local home, and no NFS shares references in the PATH, and the system is responsive until one tries to access the NFS shares.
