[jira] Commented: (CASSANDRA-757) FatClient removal causes
ConcurrentModificationException
[ https://issues.apache.org/jira/browse/CASSANDRA-757?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12889310#action_12889310 ]
Wade Simmons commented on CASSANDRA-757:
----------------------------------------
This is a more serious bug than originally thought due to CASSANDRA-1289. When this exception gets thrown, it causes GossipTimerTask to stop running until the server is restarted. Because of this, I would recommend a backport to 0.6.x (I'll offer to do the backport as well).
