Was not that hard to find with Google...

IBM

Limbo Packets
    Number of limbo packets received on the control channel. Limbo packets are sent by the primary Shared Ethernet Adapter
    when it detects that its physical network is not operational, or when it cannot ping the specified remote host (to inform
    the backup that it needs to become active).

How to resolve? This might give you a hint where to start searching.
