[jboss-jira] [JBoss JIRA] (JGRP-2095) FILE_PING rewrites files too often

FILE_PING rewrites files too often ---------------------------------- Key: JGRP-2095 URL: https://issues.jboss.org/browse/JGRP-2095 Project: JGroups Issue Type: Bug Affects Versions: 3.2.13 Reporter: Dennis Reed Assignee: Bela Ban FILE_PING.fetchClusterMembers writes its own data to file on every call. If there is an issue finding a cluster member's address, fetchClusterMembers can be called very frequently by TP's GET_PHYSICAL_ADDRESS calls. This can cause problems because while that file is being (unnecessarily) overwritten, any readers will see an empty or corrupt file. If it's bad enough JGRP-1448 is not sufficient to handle it, and readers will end up thinking the file is stale and delete it (even while it's still in progress of being written). That missing file can then cascade the problem, with other nodes not being able to find this member's address, and triggering the same problem again. There is already a scheduled task to rewrite the file occasionally, so rewriting it on every fetchClusterMembers call is not needed.
