Bela Ban created JGRP-1917: ------------------------------ Summary: FILE_PING: options to remove zombies Key: JGRP-1917 URL: https://issues.jboss.org/browse/JGRP-1917 Project: JGroups Issue Type: Enhancement Reporter: Bela Ban Assignee: Bela Ban Fix For: 3.6.3 In {{FILE_PING}} and subclasses ({{S3_PING}}, {{GOOGLE_PING}}), coordinators write the files (e.g. {{A.list}} for coord {{A}}). There's a shutdown hook that removes {{A.list}} when {{A}} crashes. However, when a coordinator is killed by kill -9, the file {{A.list}} won't get removed. The problem with this is that new members will read {{A.list}} and get delayed trying to ask {{A}} to join the cluster although {{A}}'s not alive anymore ({{B}} is and created {{B.list}}). Possible solution: implement a mechanism similar to JGRP-1915 where a coordinator removes *all files* on a view change with leaving members, and then writes its file again. -- This message was sent by Atlassian JIRA (v6.3.11#6341)
