Depends on when the last tick was sent, e.g. it may have been sent 30 
seconds before the large message is sent.

Btw,

It should join up again when one node attempts to talk to the other. Not 
sure what would trigger that in rabbit; queue/exchange/binding 
creation/deletion perhaps (due to the mnesia synchronisation that needs 
to happen as part of that).
