ISAKMP DPD_ACK_TX message - what's it mean?

Can anyone tell me what these messages in my isakmp debug buffer mean?

Re: ISAKMP DPD_ACK_TX message - what's it mean?

The router is receiving DPD hello messages from the peer (DPD_RX) and acknowledging it (DPD_ACK_TX). DPD (Dead Peer Detection) is a mechanism used for earlier detection of dead peers.
