[infinispan-issues] [JBoss JIRA] (ISPN-9801) ClusterTopologyManagerImpl hangs when restarting a node with FORK

ClusterTopologyManagerImpl hangs when restarting a node with FORK ----------------------------------------------------------------- Key: ISPN-9801 URL: https://issues.jboss.org/browse/ISPN-9801 Project: Infinispan Issue Type: Bug Components: Core Affects Versions: 10.0.0.Alpha1, 9.4.3.Final Reporter: Dan Berindei Assignee: Dan Berindei Priority: Major Fix For: 10.0.0.Beta1, 9.4.7.Final When a server is restarted with `kill -9` or similar, both the old node and the new one can be in the JGroups view for a while. Normally this shouldn't be a problem, but sometimes the new node doesn't receive the {{HeartBeatCommand}} and the coordinator cannot process any new view updates. {noformat} 14:29:19,981 INFO (jgroups-12,Test-NodeA:[]) [CLUSTER] ISPN000094: Received new cluster view for channel FORKISPN: [Test-NodeA|4] (5) [Test-NodeA, Test-NodeB, Test-NodeC, Test-NodeD, Test-NodeE] 14:29:19,982 TRACE (transport-thread-Test-NodeA-p4-t14:[ViewHandling]) [ClusterTopologyManagerImpl] Updating cluster members for all the caches.
