11.2.0.3 VIP/SCAN VIPs unreachable causing connection issue

There are always new things I find on My Oracle Support, but one interesting find was "11.2.0.3 VIP/SCAN VIP is Not Pingable After Failover Leads to Connection Issue" from note 1379498.1 because it reminds me of the problems we had with our ZFS connection after upgrading to 11.2.0.3 on Exadata.  Of course there is a workaround and the next patch of 11.2.0.3 contains the fix, as well as 11.2.0.4, but it would not hurt at all to make sure your platform is on the right version to avoid bug 13440962.
