ABSTRACT:
A process and system for distributed garbage collection in a distributed network includes transmission of a root request message tagged with a unique identifier from a suspect node to all nodes of the suspect node's inverse reference graph looking for a rooted (persistent) object. Objects respond to the root request message with an affirmative or disregard response (indicating a root or coupling to a root) tagged with the same identifier or that no relevant garbage collecting information is available from a particular branch. The suspect node, in the absence of any affirmative responses, is identified as obsolete (garbage) and may be collected. Other objects having the same identifier are identified and/or collected as garbage as well.
