FD: messages from members other than ping_dest causes missing-heartbeat count to be reset ----------------------------------------------------------------------------------------- Key: JGRP-746 URL: http://jira.jboss.com/jira/browse/JGRP-746 Project: JGroups Issue Type: Bug Reporter: Bela Ban Assigned To: Bela Ban Priority: Critical Fix For: 2.6.3, 2.7 [email from John Smith] I'm not sure FD is behaving like it should. I started a group with two members. I then suspended one instance with a kill -SIGSTOP. After a while I expected the FD protocol to suspect the suspended jvm but it did not do it. I looked at FD code and it seems like messages that do not come from ping_dest reset num_tries and thus prevent the member from being suspected. Is this intended? Why would a message from self reset num_tries? I'm using jgroups 2.6.2. Here is and the relevant part of the jgroups logs: 10:10:48,291 DEBUG [FD] sending are-you-alive msg to 192.168.128.105:47870 (own address=192.168.128.129:57685) 10:10:48,291 DEBUG [FD] heartbeat missing from 192.168.128.105:47870 (number=0) 10:11:18,293 DEBUG [FD] sending are-you-alive msg to 192.168.128.105:47870 (own address=192.168.128.129:57685) 10:11:18,293 DEBUG [FD] heartbeat missing from 192.168.128.105:47870 (number=1) 10:11:48,294 DEBUG [FD] sending are-you-alive msg to 192.168.128.105:47870 (own address=192.168.128.129:57685) 10:11:48,294 DEBUG [FD] heartbeat missing from 192.168.128.105:47870 (number=2) 10:12:18,296 DEBUG [FD] sending are-you-alive msg to 192.168.128.105:47870 (own address=192.168.128.129:57685) 10:12:18,296 DEBUG [FD] heartbeat missing from 192.168.128.105:47870 (number=3) 10:12:48,299 DEBUG [FD] sending are-you-alive msg to 192.168.128.105:47870 (own address=192.168.128.129:57685) 10:12:48,299 DEBUG [FD] heartbeat missing from 192.168.128.105:47870 (number=4) 10:12:51,265 DEBUG [FD] received msg from 192.168.128.129:57685 (counts as ack) 10:13:18,300 DEBUG [FD] sending are-you-alive msg to 192.168.128.105:47870 (own address=192.168.128.129:57685) 10:13:19,336 DEBUG [FD] received msg from 192.168.128.129:57685 (counts as ack) 10:13:45,988 DEBUG [FD] received msg from 192.168.128.129:57685 (counts as ack) 10:13:48,302 DEBUG [FD] sending are-you-alive msg to 192.168.128.105:47870 (own address=192.168.128.129:57685) 10:14:18,303 DEBUG [FD] sending are-you-alive msg to 192.168.128.105:47870 (own address=192.168.128.129:57685) 10:14:18,303 DEBUG [FD] heartbeat missing from 192.168.128.105:47870 (number=0) -- This message is automatically generated by JIRA. - If you think it was sent incorrectly contact one of the administrators: http://jira.jboss.com/jira/secure/Administrators.jspa - For more information on JIRA, see: http://www.atlassian.com/software/jira
