> HandleHttpRequest - 500, stopping does not works
> ------------------------------------------------
>
> Key: NIFI-6697
> URL: https://issues.apache.org/jira/browse/NIFI-6697
> Project: Apache NiFi
> Issue Type: Bug
> Components: Core Framework
> Affects Versions: 1.8.0
> Environment: CentOS Linux release 7.5.1804 (Core)
> Oracle jre1.8.0_181-amd64
> Reporter: Mermillod
> Priority: Critical
> Fix For: 1.10.0
>
>
> My HandleHTTPRequest does not accept anymore POST messages, after some time,
> returning 500 (port 10010).
> There is lot of file availaible on the machine (ulimit etc).
> Settings :
> * 1 thread
> * timerdriver
> * 200ms
> * 50 containerqueue (i'm pretty sure i never fill it due to low volumes of
> calls).
> "Stop Processor" does not work : it starts the stop thread, never ending.
> "Terminate Thread" seems to work (the #2 on the processor disappears), but a
> thread dump shows that *not* :
> {code:java}

> The listener is still there :

> {code:java}
> netstat -an | grep 10010
> tcp 0 0 0.0.0.0:10010 0.0.0.0:* LISTEN {code}
>
> Restarting the processor (after the "terminate thread") does not work since
> the port is already listening.
>
> Current workaround : stop/start nifi.
