Paul Ferraro created ISPN-6192: ---------------------------------- Summary: Short-term memory leak caused by RPCs that complete prior to their timeout Key: ISPN-6192 URL: https://issues.jboss.org/browse/ISPN-6192 Project: Infinispan Issue Type: Bug Components: Core Affects Versions: 8.1.1.Final, 8.2.0.Beta1 Reporter: Paul Ferraro Assignee: Paul Ferraro Priority: Blocker The CommandAwareRpcDispatcher uses the timeout executor to trigger the cancellation of an async rpc after some timeout. However, in the event that the command executes prior to the timeout (i.e. most of the time), the task remains in the timeout executor's queue. Consequently, the reference to the RspListFuture/SingleResponseFuture will remain in the executor's queue unnecessarily for the duration of the timeout. Using ScheduledThreadPoolExecutor.setRemoveOnCancelPolicy(true) should fix the problem. -- This message was sent by Atlassian JIRA (v6.4.11#64026)
