[ https://issues.jboss.org/browse/ISPN-1630?page=com.atlassian.jira.plugin.... ] Galder Zamarreño updated ISPN-1630: ----------------------------------- Description: When a node leaves, {{KeyGeneratorWorker}} can get in an infinite loop because the consistent hash doesn't return the leaver any more and {{KeyGeneratorWorker}} will never be able to generate the required number of keys. {{KeyAffinityServiceImpl}} installs a listener for {{TopologyChangeEvents}} that is supposed to adjust the queues and prevent this problem. However, it doesn't work if {{KeyGeneratorWorker}} is already generating keys, because it needs to acquire the {{maxNumberInvariant}} write lock and KeyGeneratorWorker is never going to release the {{maxNumberInvariant}} read lock. What's worse, because the listener is synchronous, it also blocks the cache view installation and other cluster changes will be ignored.
