[jboss-user] [JBoss Cache: Core Edition] - Problems in websphere cluster environment
We are having problems with JbossCache v1.4.1.SP9 and JGroups 2.4.1 in Websphere 6.1
cluster environment.
Randomly, we get the following errors in the log:
JChannel I org.jgroups.JChannel handleExit received an EXIT event, will leave the
channel
JChannel I org.jgroups.JChannel$CloserThread run closing the channel
NAKACK W org.jgroups.protocols.pbcast.NAKACK handleMessage node1] discarded message
from non-member node1, my view is MergeView::[node1|30] [node1, node2],
subgroups=[[node1|0] [node1], [node2|29] [node2]]
Also we get:
NAKACK W org.jgroups.protocols.pbcast.NAKACK send [node1] discarded message as
start() has not been called, message: [dst: , src: (1 headers), size = 146 bytes]
The cluster has 2 nodes which are called node1 and node2 for simplicity in the post.
After a couple of seconds in which node1 continues throwing those messages, we get:
GMS W org.jgroups.stack.Protocol receiveDownEvent exception:
QueueClosedException
ProtocolStack E org.jgroups.stack.ProtocolStack down no down protocol available !
...
UNICAST W org.jgroups.protocols.UNICAST setProperties window_size is deprecated and

TreeCache I org.jboss.cache.TreeCache viewAccepted viewAccepted(): [node10] [node1]
JChannel I org.jgroups.JChannel$CloserThread run fetching the state
(auto_getstate=true)
JChannel I org.jgroups.JChannel$CloserThread run state transfer failed
And no more messages for node1. In node2 we have no special messages of this problem.
The configuration file of jbosscache is:

I will appreciate any help. Thanks.
