[jboss-jira] [JBoss JIRA] Commented: (JGRP-217) unplugging of network cable makes jgroups behave weirdly

unplugging of network cable makes jgroups behave weirdly -------------------------------------------------------- Key: JGRP-217 URL: http://jira.jboss.com/jira/browse/JGRP-217 Project: JGroups Issue Type: Bug Affects Versions: 2.2.8, 2.2.9, 2.3 Reporter: Manoranjan Sahu Assigned To: Bela Ban Fix For: 2.4 Attachments: logs.jar, mping.xml, pull-tcp.xml, pulltheplug.xml Hi, I am using jgroups 2.2.9 for communication in my cluster. I was checking the behaviour of jgroups to network fluctuation. for that I manually unplug the network cable and plug it back after some time. But jgroups keeps sending suspected messages and never bring that into the cluster. I have two machines in my cluster A(10.200.1.92) & B(10.200.1.74). I unplug the cable in machine B. and plug it back . but B never joined the cluster. Please find the attachment for the log files from both the machines. I am using TCP based communication. I set up my protocol stack using . MPING,MERGE2,FD,VERIFY_SUSPECT,pbcast.NAKACK,pbcast.STABLE,VIEW_SYNC,pbcast.GMS. The following are the confuguration in both the machines. configuration setting in Machine-A notificationbus.properties: TCP(bind_addr=boca;recv_buf_size=200000;send_buf_size=100000;loopback=true; start_port=7880): MPING(timeout=4000;bind_to_all_interfaces=true;mcast_addr=228.8.8.8;mcast_port=7500; ip_ttl=8;num_initial_members=4;num_ping_requests=1): MERGE2(max_interval=10000;min_interval=5000): FD(timeout=2000;max_tries=3): VERIFY_SUSPECT(timeout=1500;down_thread=false;up_thread=false): pbcast.NAKACK(max_xmit_size=60000;gc_lag=50; retransmit_timeout=100,200,300,600,1200,2400,4800): pbcast.STABLE(stability_delay=1000;desired_avg_gossip=20000;down_thread=false; up_thread=false;max_bytes=0): VIEW_SYNC(avg_send_interval=60000;down_thread=false;up_thread=false): pbcast.GMS(print_local_addr=true;join_timeout=5000;join_retry_timeout=2000;shun=true) ------------------------------- configuration setting in Machine-B notificationbus.properties: TCP(bind_addr=rizal;recv_buf_size=200000;send_buf_size=100000; loopback=true;start_port=7880): MPING(timeout=4000;bind_to_all_interfaces=true;mcast_addr=228.8.8.8; mcast_port=7500;ip_ttl=8;num_initial_members=4;num_ping_requests=1): MERGE2(max_interval=10000;min_interval=5000):FD(timeout=2000;max_tries=3): VERIFY_SUSPECT(timeout=1500;down_thread=false;up_thread=false): pbcast.NAKACK(max_xmit_size=60000;gc_lag=50; retransmit_timeout=100,200,300,600,1200,2400,4800): pbcast.STABLE(stability_delay=1000;desired_avg_gossip=20000;down_thread=false; up_thread=false;max_bytes=0): VIEW_SYNC(avg_send_interval=60000;down_thread=false;up_thread=false): pbcast.GMS(print_local_addr=true;join_timeout=5000;join_retry_timeout=2000;shun=true) ----------------
