Christoph John commented on DIRMINA-1177:
-----------------------------------------
OK, maybe you should just test if a newer version solves your problem?!
> The Connector will blocked when execute dispose, And multiple threads are
> leaking

> Key: DIRMINA-1177
> URL: https://issues.apache.org/jira/browse/DIRMINA-1177
> Project: MINA
> Issue Type: Bug
> Components: Core
> Affects Versions: 2.0.13
> Reporter: Vegeta
> Priority: Major
> Attachments: RpcClien3.java, image-2024-01-08-16-53-27-846.png,

> In an old project, a RpcClient using mina 2.0.13 version has a memory leak.
> After investigation, it was found that many NioProcessor and
> NioSocketConnector were not recycled, and the number of threads was
> continuously increasing (the traffic did not increase).
> Below is the RpcClient code used in the project. After reading, I also found
> some problems:
> [^RpcClien3.java]
> {code:java}
> new RpcClient3().start();{code}
> 1.session close is not right
> {code:java}
> RpcClient#close()
> future.getSession().close(false);
> // this future is ConnectFuture,not CloseFuture
> futureUInterrupt = future.awaitUninterruptibly(CONNECTOR_WORKER_TIMEOUT);
> {code}
> 2.RpcClient#close has concurrent calls
> {code:java}
> 1.RpcClient#startHealthCheck
> 2.RpcClient#activateConnectionSensor{code}
>
> But I still can't reproduce this problem, My leader want to locate the
> problem as much as possible before trying on the prod environment, such as
> updating the version, modifying session close to
> future.getSession().close(true) and wait().
