Node heartbeat checks are failing with TCP ------------------------------------------ Key: JGRP-2385 URL: https://issues.jboss.org/browse/JGRP-2385 Project: JGroups Issue Type: Feature Request Affects Versions: 3.6.19 Environment: Windows Reporter: Rashmi Acharya Assignee: Bela Ban Priority: Critical Hi Bela, One of our customer which is still on 3.4.0 Jgroups are facing issue with Node -Node cluster heartbeat communication with TCP. Node is not responding intermittently and moved out of cluster group (around 3 nodes as part of the cluster along with 3 container nodes) when port_range=0 setting, it works fine.. Can you please explain the significance of this with TCP option ? What is the recommended value which is suggested with Jgroups ? Here is the property String: jgroups_cluster.property_string=TCP(bind_addr=10.1.231.73;bind_port=8141):TCPPING(initial_hosts=10.1.231.73,10.1.231.10;port_range=1;timeout=5000;num_initial_members=2):MERGE2(min_interval=3000;max_interval=5000):FD_ALL(interval=5000;time out=20000):FD(timeout=5000;max_tries=48;level=ERROR):VERIFY_SUSPECT(timeout=1500):pbcast.NAKACK(retransmit_timeout=100,200,300,600,1200,2400,4800;discard_delivered_msgs=true):pbcast.STABLE(stability_delay=1000;desired_avg_gossip=20000;max_bytes=0):pb cast.GMS(print_local_addr=true;join_timeout=5000)
