[jboss-jira] [JBoss JIRA] (JGRP-1755) TP: dropping message to wrong destination in a shared transport

TP: dropping message to wrong destination in a shared transport --------------------------------------------------------------- Key: JGRP-1755 URL: https://issues.jboss.org/browse/JGRP-1755 Project: JGroups Issue Type: Bug Reporter: Bela Ban Assignee: Bela Ban Priority: Minor Fix For: 3.4.2, 3.5 Attachments: bla3.java, shared.xml TP has a check whether the dest of incoming unicast messages matches its local address (or the local address in the ProtocolAdapter if a shared transport is used). Messages whose dest != local address are dropped. However, in the following scenario, we can have spurious warnings for 2 minutes (by default): * 2 processes with 2 members on a shared transport each (see attached shared.xml and bla3.java) ** Start 2 bla2 instances on the same box * On the second instance, a member leaves and immediately rejoins (press [2] on the second member) * For some reason, the leaving member didn't receive the {{LEAVE_RSP}} unicast message from the coordinator (first member) * The newly joined member now receives the {{LEAVE_RSP}} unicast from the coordinator, but now it is a different member and therefore has a different local address, so we see the warning * This will continue for 2 minutes, until the connection to the unknown member is closed by the coordinator (configurable) TODOs: * Investigate why the {{LEAVE_RSP}} unicast is not received by the leaving member * In the warning, add the sender's address and print the headers of the message so it's easier to find the culprit
