Jboss 4 clustering problem
bw149 Oct 22, 2012 4:59 PMHi,
We have two servers running using jboss 4.0.0 (in redhat enterprise 5.0) and joined as a cluster. It worked fine until we updated the server cpu from one quad core cpu to two quad core cpu. After the update the cluster is not working any more after running 20-30 minutes. Two servers worked as independent server. Any idea of what might be wrong and how it can be fixed. Will really appreciate if anyone can help.
Here is the jgroup configration of cluster-service.xml (see attached file)
...
<!-- The JGroups protocol configuration -->
<attribute name="PartitionConfig">
<Config>
<!-- UDP: if you have a multihomed machine,
set the bind_addr attribute to the appropriate NIC IP address -->
<!-- UDP: On Windows machines, because of the media sense feature
being broken with multicast (even after disabling media sense)
set the loopback attribute to true -->
<UDP mcast_addr="225.0.0.10" mcast_port="45566"
ip_ttl="32" ip_mcast="true"
mcast_send_buf_size="800000" mcast_recv_buf_size="150000"

<pbcast.STATE_TRANSFER up_thread="true" down_thread="true" />
</Config>
</attribute>
...
Thanks a lot!
