[infinispan-issues] [JBoss JIRA] Created: (ISPN-1388) Eviction scheduled executor never shutdown

Eviction scheduled executor never shutdown ------------------------------------------ Key: ISPN-1388 URL: https://issues.jboss.org/browse/ISPN-1388 Project: Infinispan Issue Type: Bug Components: Eviction Affects Versions: 5.0.1.FINAL Reporter: Galder Zamarreño Assignee: Galder Zamarreño Priority: Critical Fix For: 5.1.0.ALPHA2 , 5.1.0.FINAL Attachments: threaddump.txt At the end of the testsuite, there're about ~900 scheduled eviction threads lying around. Is the scheduled eviction executor thread shutdown at all??? What's not very clear here is whose responsibility is to shutdown executor services. For example, take @ComponentName(ASYNC_TRANSPORT_EXECUTOR), this is injected into: CacheImpl, RpcManagerImpl, QueryInterceptor and JGroupsTransport. Who's supposed to shut it down? Right now, it's RpcManagerImpl doing it, which is a named cache component. This opens another interesting question: Are ExecutorService components global, or per cache? Or both? For example, take ASYNC_TRANSPORT_EXECUTOR, it's injected to Transport, so must be global. But then you see RpcManagerImpl, which is a named cache component shutting it down? Surely that cannot be right. Going back to the original concern, take KnownComponentNames.EVICTION_SCHEDULED_EXECUTOR which is used by EvictionManagerImpl, this is never shutdown by anyone, which matches what's seen in the thread dump. -- This message is automatically generated by JIRA.
