Robert Andersson created ISPN-4271: -------------------------------------- Summary: ExecutorService may deadlock in RpcManagerImpl.invokeRemotelyInFuture Key: ISPN-4271 URL: https://issues.jboss.org/browse/ISPN-4271 Project: Infinispan Issue Type: Bug Components: Core Affects Versions: 6.0.2.Final Environment: Ubuntu 14.04 Reporter: Robert Andersson Assignee: Dan Berindei Priority: Minor If the number of tasks active gets bigger than the size of the asyncExecutor workQueue, then invokeRemotelyInFuture will deadlock. The deadlock is caused by DefaultExecutorFactory using ThreadPoolExecutor.CallerRunsPolicy(), so when the workQueue overflows, invokeRemotelyInFuture ends up blocking in futureSet.await() because it never gets to futureSet.countDown(). The logic basically assumes CallerRunsPolicy will never trigger. -- This message was sent by Atlassian JIRA (v6.2.3#6260)
