[ https://issues.jboss.org/browse/JGRP-2237?page=com.atlassian.jira.plugin.... ] kfir avraham edited comment on JGRP-2237 at 11/29/17 7:01 AM: -------------------------------------------------------------- i attached logs from server_A, server_B, and conf file. in this case (after upgrade to version 4.0.8) it is look better but from some reason after a few restarts, server_A doesn't sent a join message to the other machine, and create new view with 'is_coord-true'. any idea what could be the reason for that? BTW, we must to use in ' port_range="0" ', because we want to use only in this port, and it worked perfect in 3.6.11 version (we upgraded the version because security issue). when i set ' port_range="5" ', they not discovered each other from the beginning. *+Log in trace mode:+* Nov-28-2017 23:31:36 GMT-12:00 [org.jgroups.protocols.TCP] [main] [DEBUG] - thread pool min/max/keep-alive: 2/30/60000 use_fork_join=false, internal pool: 0/4/30000 (2 cores available) Nov-28-2017 23:31:36 GMT-12:00 [org.jgroups.protocols.pbcast.NAKACK2] [main] [TRACE] - null: set max_xmit_req_size from 0 to 247600 Nov-28-2017 23:31:36 GMT-12:00 [org.jgroups.protocols.UNICAST3] [main] [TRACE] - null: set max_xmit_req_size from 0 to 247600 Nov-28-2017 23:31:36 GMT-12:00 [org.jgroups.protocols.pbcast.STABLE] [main] [TRACE] - clm-tlv-spih31-6939: stable task started Nov-28-2017 23:31:36 GMT-12:00 [org.jgroups.protocols.TCPPING] [main] [TRACE] - clm-tlv-spih31-6939: sending discovery request to 10.63.16.13:8102 Nov-28-2017 23:31:36 GMT-12:00 [org.jgroups.protocols.TCP] [main] [TRACE] - clm-tlv-spih31-6939: sending msg to 10.63.16.13:8102, src=clm-tlv-spih31-6939, headers are TCPPING: [GET_MBRS_REQ cluster=HACluster initial_discovery=true], TP: [cluster_name=HACluster] Nov-28-2017 23:31:36 GMT-12:00 [org.jgroups.protocols.TCP] [TQ-Bundler-7,clm-tlv-spih31-6939] [TRACE] - 10.63.16.3:8102: +*connecting to 10.63.16.13:8102*+ Nov-28-2017 23:31:36 GMT-12:00 [org.jgroups.protocols.TCP] [Connection.Receiver [10.63.16.3:50534 - 10.63.16.13:8102]-9,clm-tlv-spih31-6939] [TRACE] - 10.63.16.3:8102: +*removed connection to 10.63.16.13:8102*+ Nov-28-2017 23:31:36 GMT-12:00 [org.jgroups.protocols.TCP] [TcpServer.Acceptor[8102]-5,clm-tlv-spih31-6939] [TRACE] - 10.63.16.3:8102: +*accepted connection from 10.63.16.13:8102*+ Nov-28-2017 23:31:37 GMT-12:00 [org.jgroups.protocols.pbcast.GMS] [main] [TRACE] - clm-tlv-spih31-6939: *+no members discovered after 1029 ms:+* creating cluster as first member Nov-28-2017 23:31:37 GMT-12:00 [org.jgroups.protocols.pbcast.NAKACK2] [main] [DEBUG] - [clm-tlv-spih31-6939 setDigest()] existing digest: [] new digest: clm-tlv-spih31-6939: [0 (0)] resulting digest: clm-tlv-spih31-6939: [0 (0)] Nov-28-2017 23:31:37 GMT-12:00 [org.jgroups.protocols.pbcast.GMS] [main] [DEBUG] - clm-tlv-spih31-6939: installing view [clm-tlv-spih31-6939|0] (1) [clm-tlv-spih31-6939] was (Author: kavraham): i attached logs from server_A, server_B, and conf file. in this case (after upgrade to version 4.0.8) it is look better but from some reason after a few restarts, server_A doesn't sent a join message to the other machine, and create new view with 'is_coord-true'. any idea what could be the reason for that?
