[jboss-jira] [JBoss JIRA] (JGRP-1674) STOP_FLUSH race condition

Dennis Reed created JGRP-1674: --------------------------------- Summary: STOP_FLUSH race condition Key: JGRP-1674 URL: https://issues.jboss.org/browse/JGRP-1674 Project: JGroups Issue Type: Bug Affects Versions: 2.6.21 Reporter: Dennis Reed Assignee: Bela Ban There is a race condition in STOP_FLUSH when a node joins the cluster. JOINER sends JOIN_REQ to MASTER MASTER does a flush on the existing members (START_FLUSH, ...) MASTER sends JOIN_RSP MASTER sends STOP_FLUSH JOINER receives JOIN_RSP JOINER fetches state, sends START_FLUSH JOINER receives STOP_FLUSH from MASTER onStopFlush never verifies that the current node was part of the FLUSH, and therefore is valid for the current node. So this STOP_FLUSH corrupts JOINER's FLUSH by resetting all the member variables (and probably unblocking). -- This message is automatically generated by JIRA.
