Carsten Ziegeler commented on FELIX-4663: ----------------------------------------- I've added some code in rev 1629402 which should handle the case for the RejectedExecutionException. Not sure though if we should just catch REE or all exceptions (like it is now) > Potential memory leak in AsyncDeliveryTask > ------------------------------------------ > > Key: FELIX-4663 > URL: https://issues.apache.org/jira/browse/FELIX-4663 > Project: Felix > Issue Type: Bug > Components: Event Admin > Affects Versions: eventadmin-1.3.2 > Reporter: Hartmut Lang > Assignee: Carsten Ziegeler > Fix For: eventadmin-1.4.4 > > > EventAdmin 1.3.2 can create an OutOfMemory condition caused by not delivered > async events. > The problem can occur if an interrupted thread issues an async event (e.g. > log-event). > In EventAdmin 1.3.2 the async-delivery uses DefaultThreadPool based on > PooledExecutor. > If the already interrupted thread enters the execute-method in PooledExecutor > an InterruptedException is thrown before the TaskExecutor was added to the > Thread-Pool. > This Exception is catched(not handled, only logged) in the DefaultThreadPool. > As a result the TaskExecuter was not scheduled in the ThreadPool but is still > part of the m_running_threads. > All new events are added to the pool of the TaskExecuter, adding in a > increasing LinkedList. The TaskExecutor is never started again. Memory is > leaking. > Seems that 1.4.x is not vulnerable related to interrupted threads. But the > same catch-and-not-handle block is used in 1.4.x. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
