JGroupsTransport should only send messages to nodes in the cluster view ----------------------------------------------------------------------- Key: ISPN-9062 URL: https://issues.jboss.org/browse/ISPN-9062 Project: Infinispan Issue Type: Bug Components: Core Affects Versions: 9.2.1.Final Reporter: Dan Berindei Assignee: Dan Berindei Fix For: 9.2.2.Final, 9.3.0.Alpha1 {{JGroupsTransport}} only waits for responses from nodes in the JGroups cluster view, but it still sends messages to all the nodes specified as a target. The idea was to optimize the common case by avoiding a {{HashSet.contains()}} call. However, when a node is not in the view, messages to it still pass through the entire JGroups stack, and UNICAST3 keeps those messages in a send table for a long time ({{UNICAST3.conn_expiry_timeout}}, changed with ISPN-9038 from {{0}} (unlimited) to 2 minutes (JGroups default)). Having a potentially unlimited number of messages of non-members, each with its own send table, makes it much harder to estimate memory usage.
