  • Only occurs when a cluster LIF is hosted on either e0a / e0b cluster ports
  • No messages regarding ports e0a / e0b links going down or up
  • Configuring a 3rd cluster port (eg. e0f) and hosting a cluster LIF on this for redundancy does not prevent the panic which still occurs so long as a LIF is on e0a or e0b
