[jboss-jira] [JBoss JIRA] Created: (JGRP-1326) Gossip Router dropping message for node that is in its routing table list

Gossip Router dropping message for node that is in its routing table list ------------------------------------------------------------------------- Key: JGRP-1326 URL: https://issues.jboss.org/browse/JGRP-1326 Project: JGroups Issue Type: Bug Affects Versions: 2.10 Environment: Linux, Windows Reporter: vivek v Assignee: Bela Ban We are using Tunnel protocol with two Gossip Routers. For some reason we start seeing lots of suspect messages in all the nodes - there are 7 nodes in the group. Six of the nodes (including the coordinator) was suspecting node A (manager_172.27.75.11) and node A was suspecting the coordinator, but no new view was being created. After turning on the trace on both gossip routers (GR1 and GR2) I see following for every message that's sent to Node A (manager_172.27.75.11), {noformat} 2011-05-20 15:56:21,186 TRACE [gossip-handlers-6] GossipRouter - cannot find manager_172.27.75.11:4576 in the routing table, routing table= 172.27.75.11_group: probe_172.27.75.13:4576, collector_172.27.75.12:4576, probe_172.27.75.15:4576, manager_172.27.75.11:4576, probe_172.27.75.16:4576, probe_172.27.75.14:4576 {noformat} Now, the issue is the routing table does indeed shows that there is "manager_172.27.75.11" - so why is the GR dropping messages for that node. I suspect that somehow the Gossip Router has got some old entry which has not been cleaned up - different UUID with same logical address. I tried going through the GossipRouter.java code, but couldn't find how would this be possible. As I understand a node randomly chooses a GR if there are multiple of them for its communication. Each GR would keep a separate list of physical addresses for each node - so is it possible somehow it uses physical address instead of UUID for cleaning/retrieving the node list? This seems to be creating big issue and the only work around is to restart the Gossip Routers. -- This message is automatically generated by JIRA.
