    [ https://jira.jboss.org/jira/browse/JGRP-1018?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12480019#action_12480019 ] 

Bulat Nigmatullin commented on JGRP-1018:
-----------------------------------------

Our cluster consist of 15 servers. When servers upgraded they are all stopped, then new started one by one. During some servers startup on those who already in cluster this error occur. When error arises then joining server prints 'could not flush' and cannot join to the cluster. After few restarts server successfully joins but others in cluster have this errors in log files.
