Hi Guys,

I have my cluster config like so



  | <attribute name="ClusterConfig">
  |          <config>
  |             <UDP mcast_addr="228.10.10.10"
  |                  mcast_port="45588"
  |                              singleton_name="transport_one"
  |                  tos="8"
  |                  ucast_recv_buf_size="20000000"
  |                  ucast_send_buf_size="640000"
  |                  mcast_recv_buf_size="25000000"
  |                  mcast_send_buf_size="640000"
  |                  loopback="false"
  |                  discard_incompatible_packets="true"
  |                  max_bundle_size="64000"
  |                  max_bundle_timeout="30"
  |                  use_incoming_packet_handler="true"
  |                  ip_ttl="2"
  |                  enable_bundling="false"
  |                  enable_diagnostics="true"
  | 
  |                  use_concurrent_stack="true"
  | 
  |                  thread_naming_pattern="pl"
  | 
  |                  thread_pool.enabled="true"

  |                  thread_pool.rejection_policy="Run"
  | 
  |                  oob_thread_pool.enabled="true"
  |                  oob_thread_pool.min_threads="1"
  |                  oob_thread_pool.max_threads="4"
  |                  oob_thread_pool.keep_alive_time="10000"

  |                  oob_thread_pool.rejection_policy="Run"/>
  | 
  |             <PING timeout="2000" num_initial_members="3"/>
  |             <MERGE2 max_interval="30000" min_interval="10000"/>
  |             <FD_SOCK/>
  |             <FD timeout="10000" max_tries="5" shun="true"/>
  |             <VERIFY_SUSPECT timeout="1500"/>
  |             <pbcast.NAKACK 
  |                            use_mcast_xmit="false" gc_lag="0"
  |                            retransmit_timeout="300,600,1200,2400,4800"
  |                            discard_delivered_msgs="true"/>
  |             <UNICAST timeout="300,600,1200,2400,3600"/>
  |             <pbcast.STABLE stability_delay="1000" desired_avg_gossip="50000"
  |                            max_bytes="400000"/>
  |             <pbcast.GMS print_local_addr="true" join_timeout="5000"
  |                         shun="false"
  |                         view_bundling="true" 
view_ack_collection_timeout="5000"/>
  |             <FRAG2 frag_size="60000"/>
  |             <pbcast.STREAMING_STATE_TRANSFER />
  |             <!-- <pbcast.STATE_TRANSFER/> -->
  |             <pbcast.FLUSH timeout="0"/>
  |                     
  |          </config>
  |       </attribute>

Now what I am interested in is the these 2.





  | <FD timeout="10000" max_tries="5" shun="true"/>
  | ........
  |                       <pbcast.GMS print_local_addr="true" 
join_timeout="5000"
  |                         shun="false"
  |                         view_bundling="true" 
view_ack_collection_timeout="5000"/>
  | 

Now if a node goes becomes unresponsive for a certain time and leaves the 
group, would be be allowed back in if he recovers with the current config like 
so??

I have read here 
http://www.jgroups.org/javagroupsnew/docs/manual/html_single/index.html#d0e2873 
I need to set both to false.

Would the above configuration stop a node rejoining the group if it left??

Thanks,
LL
