[infinispan-issues] [JBoss JIRA] (ISPN-6665) StateTransferManager should be the first component to stop

Brad Maxwell created ISPN-6665: ---------------------------------- Summary: StateTransferManager should be the first component to stop Key: ISPN-6665 URL: https://issues.jboss.org/browse/ISPN-6665 Project: Infinispan Issue Type: Bug Components: Core Affects Versions: 8.2.0.CR1 Reporter: Brad Maxwell Assignee: Dan Berindei Fix For: 8.2.1.Final, 9.0.0.Alpha1, 8.1.4.Final When a cache stops, it first removes the component registry from the {{GlobalComponentsRegistry}}'s {{namedComponents}} map, which means the node (let's call it {{A}}) will reply with a {{CacheNotFoundResponse}} to any remote command. Another node {{B}} trying to execute a write/transactional command will receive the {{CacheNotFoundResponse}}, assume that a new cache topology with id {{current topology id + 1}} is coming soon, and wait for that new topology before retrying. Normally this is not a problem, because {{StateTransferManagerImpl.stop()}} sends a {{CacheTopologyControlCommand(LEAVE)}} to the coordinator quickly enough, then {{B}} receives the {{current topology id + 1}} topology and retries the command. But in some cases, the cache components that stop before {{StateTransferManagerImpl}} can take a long time to do so. In particular, because of {{ISPN-5507}}, {{TransactionTable}} can block for {{cacheStopTimeout}} if there are remote transactions in progress, even though the cache can no longer process remote commands. We should give {{StateTransferManagerImpl.stop()}} a priority of {{0}}, so that the {{CacheTopologyControlCommand(LEAVE)}} comand is sent as soon as possible. -- This message was sent by Atlassian JIRA (v6.4.11#64026)
