1. A computer implemented method for communicating data in a clustered computing system, the method comprising: detecting an occurrence of a first event at a first node of the system; detecting an occurrence of a second event at the first node of the system; determining that the first event is identical to the second event, and the occurrence of first event and the occurrence of the second event are therefore a first occurrence and a second occurrence of an identical event; appending a notification including the information describing the identical event onto an existing message, wherein the notification is appended only once for both the first occurrence and the second occurrence, the notification is not appended twice, once for each occurrence, and the message was destined to be propagated to a second node; and propagating the message along with the information describing the identical event to the second node.
